That said, I'm having a bit of trouble finding attachment chain. I can get the individual links from McMaster-Carr (at about $1.85 each--ouch!), and I can't seem to find them anywhere on Stock Drive Products. Any leads on where to get these things a bit cheaper and/or together?

An alternate solution would be to use table-top or flat-top conveyor chain from McMaster. Comes in Delrin and stainless (if you can spare the weight) and they have drive sprockets, too.
Or... another interesting conveyor product is Intralox. It has been used on several large scale RC tanks. RC tanks with paintball guns for main armaments and Wi-Fi cameras - how sweet is that! I've thought about building one with a Vex controller!!
I've really thought about trying it out to see how durable Intralox would be for FRC competition. Here's a great summary of using Intralox 900 series to build a sweet WWII
German JgPz 38(t) Hetzer, but I'd look at the 800 series it's a little stronger.
