Looking for Botcon 2010 + 2011 Figures

Greetings anyone looking to depart with parts of their Botcon hauls.
Currently, I'm trying to piece together sets from both 2010 AND 2011. Here's the deal though, I have an overall price in my head for each set, so the cheaper I can get one piece, the more I'll be willing to pay for another. I imagine it will be much easier to find 2010's figures piecemeal compared to 2011's, so I'd prefer to start there. I WILL NOT BE BUYING COMPLETE SETS! I don't have the money to plop down on a whole set, so I'm aiming for 1 or 2 figures per transaction. Follow so far? Good!
Here's what I'm looking for:
2010:
Clench
Pyro
Streetstar
Breakdown
Sky-byte
Sky Shark
Land Shark
Sea Shark
Slicer
Doublepunch
Scorch w/ Ravage
I'd like to get Streetstar and Pyro pretty cheap, as I believe the other 3 in the box set are the higher demand/priced figures.
2011:
Motormaster
Breakdown
Wildrider
Dragstrip
Deadend
Toxitron
Ironfist
Sideswipe
Autotrooper #1
Autotrooper #2
Autotrooper #3
I believe that Toxi and Ironfist will be the easiest of the set to get cheap, but you're welcome to surprise me.
