CG/Scarface (AKA scarred Cobra Officer) is a good set, too. It's probably not going to be the easiest to find; it's older, and a definite army builder piece.
If you're lucky enough to find it, Tomax/Xamot is a great set, too. I wish I'd picked up an extra back in the day, but it's tough to get it now.
$40 shipped for what you can get from BBTS is a great deal. Flash is especially elusive, so I would take advantage of that.
Beach Head/
Snow Serpent, I'd wait until TRU runs a sale. They're doing that a lot. Most TRU's have a ton of the ROC version, which is the same except with camo on the pants (which actually looks better, anyway).
Mindbender... Mindbender... Damn, he's tough to get. He was only in a seven-pack of army builders, and fucked up the set since he's definitely not an army builder himself. I have no idea where you could get one. Well, I take that back. I snatched up two extra sets at Ross when they showed up for $16, so I've actually got a total of three Mindbenders. I could probably take one out of my display where Dr Mindbender and his clones try to take over an army of cloned Snake Eyeses.
