Well, fellow Arizonian, all of those figures are hobby kit style figures and last I knew were hard (if not impossible) to come by.
I forgot the guy's name, but those are all done by a fan. He's the same guy who made those amazingly toon-accurate Cyclonus, Wheelie, and Octane toys.
JizaiToys (the site the picture is linked from) does those in addition to the ^^^ Transformers. I'd definitely go after those given the opportunity, even if they are expensive kits.
