As my items are loose, and what I'm interested in acquiring will also likely be loose, I would like to meet at local comic and toy conventions in the area to buy, sell, or trade these items. I simply feel more comfortable knowing that the person who acquires my item is satisfied with the price and condition. Below is a list of items I have purchased (all at retail stores) I wish to sell or trade. All of my items include their accessories and instructions, and in some cases comics, character cards, and package backings. Tentative prices will be listed.
I will update this post as necessary, and this initial posting will likely be incomplete as I am working off memory just to get this started.
For Sale
Armada
Powerlinx Optimus Prime - $40
I original purchased POP with the hope that I could complete the set with Jetfire and Overload. Unfortunately for me, I simply do not have the money to get this done. At this time I would be happy to help someone else complete their Powerlinx set, or even provide a backup POP.
Energon
Hot Shot - $10
I picked Hot Shot up because of his resemblance to Bumblebee, and because I like his weapon. I'm ready to part with him. I have his card.
Downshift - $10
A dead ringer for Wheeljack, I still don't know why that's not his official name. I picked him up to link with Rodimus. I have his card.
Cyberton
Hot Shot - $10
I love the homage to Hot Rod. I have his poster.
Excellion - Need an offer
Not sure I want to part with this one. This is the version with flames. I wish the wings would have been orange instead of that almost completely clear blue. This is an item I'd probably look more to trade than sell, so that's why I'm not listing a price. I have his poster.
Universe 2.0
Springer - $20
I thought I'd want Springer more than Ratbat, but I like the latter more than the former. I do have the comic, but outside of an offer I see that as something to include in a trade.
Transformers Movie
Premium Barricade - Need an offer
I like this Decepticon. The mold has its flaws, but I have no regrets about the paint. I'll sell for the right price or trade. I have his package backing.
Cliffjumper - Need an offer
I like the repaint. I like the mold. I plan on posting him posed with a big bazooka soon in the collections forum. I will sell or trade, but like Barricade this is not an easy part for me. I have his package backing.
Blackout - $15
I liked the mold, I liked the character, so I picked him up. Unfortunately some of the gold paint on his radar globe is chipped. I have no idea why that happened, so I'm not asking for full price.
Thundercracker - $20
I picked him up before Deep Space Starscream was released. I like the latter better, so if someone missed out on movie TC, I've got one sitting right here.
Revenge of the Fallen
Preview Bumblebee - $10
I wanted a Bumblebee in the right colors, so I picked this up. I had to trim the end of the missile so it could fit properly into the arm cannon. I also figured out how to transform the figure without removing the weapon. I have his package backing.
Cannon Bumblebee - $10
This became my favorite B until my wish was granted and BBBB came out. I even added an

Dead End (deluxe) - $10
Cool mold, especially the head. I thought I would really like this redeco of Sideways more than I do. I have his package backing.
Wish List
I have Energon Arcee and would like the Blue movie repaint and the movie Elita-One version.
Continuing with Arcee, I am interested in all three decos of deluxe Movie Arcee (purlpe, pink, All-Spark black).
I also have interest in RotF Arcee, in particular the repainted version that comes in the Target two-pack exclusive.
Energon Checkpoint, the repaint of Energon Rodimus has my interest.
Energon Prowl has my interest as well.
I never saw Universe 2.0 Vector Prime, so I never had a chance to pass on him. I was planning to pick him up, but I never had the chance.
I would very much like the Minicon Energon Saber team.
I noticed a three-pack that included Ransack GTS. I'd like him, though I think I'll have to fix his rear wheel assembly like I did with the original.
I did not pick up the Target Exclusive Dirge vs. Roadbuster two-pack. I would love to get Roadbuster as that is a great mold. As I have the comic for this pack that came with the other pack, I'd be happy to include it for trade value.
Another two-pack release I avoided had the only domestic Classics Skywarp. While we may get an update, if someone has an extra I am interested.
Finally, I overlooked movie Legends Scorponok. If someone has him and doesn't want him, I do.

So, that's what I have and what I'm looking for. Feel free to ask questions below or via PM. The cash prices listed are more of a guide. I do believe they are worth what I'm asking, but it's not like I'm setting anything in stone, especially if a trade is involved. I keep everything nicely stored to minimize dust and prevent damage.
