I've got a quite a bit.
City Commander and rifle & shoulder missiles
Protector & Sidearm
Crossfire 1 (Superion)
Crossfire 2 A&B (Bruticus)
Blesser (and the uncomfortable fact that it took a free toy to get me to donate to the Tsunami Relief Fund)
G3 Trailer (highly recommended!)
And I just got CA-01 Warcry yesterday to make into G2 Swindle!
Battle Tanker (KO to make into Scourge but I do intend to get the original)
Yellow Giant sets 1 and 2 are in my POL awaiting set 3 and Green to ship!
Ark playset (which I sold because it didn't hold all of my Season 1 Autobots on the shelf)
Two of the Shadow Warrior figures repainted into screen accurate Rumble and Frenzy.
Upsized KO of their Reflector to repaint.
Megavolt Robot Factory: Deluxe Starscream's coronation set
MP Starscream's coronation set
Battle Roller (which I regret selling)
MP Megatron add-on parts (which I sold because I never transform him int a gun anyway)
BTS Nemesis Trailer
Impossible Toys first Quintesson
TFCon Nightbird (which I sold)
Botcon '07 Vector Sigma
Beast Wars Golden Disk set
Animated Allspark set
I had the original metal Key to Vector Sigma but I lost it when I moved.
TFCon Stronghold which I am selling (Check out below!)
Blood set for Bludgeon
Getting a Centurion at some point
The original Wreck Gar chest, pads, wheel shield, and ax and the Bludgeon chest & legs and an Inferno headpiece are both on order.
I had the Natobot Roadbuster set as well and have various one of a kind and limited run garage kit items and sets. Soon enough I'll have my set for Botcon Octopunch (and hopefully so will everyone who wants one!) and a bunch of stuff from Shapeways like an abdomen filler for Energon/ROTF Superion, and heads and weapons and the like. Plus more Reprolabel sets than I could even hope to name.
And I still found enough money in the couch to give to Hasbro from time to time.
