I actually/finally bought the Devastator gift set at the same "road trip" Wal-Mart I mentioned in my last post of this thread. $29.76 plus tax.
I didn't realize that two of the five toys are repaints of two others, but it isn't terribly bothersome, but does cause it to pale in comparison to the variety of the vintage Constructicons. My main gripe is that it's nearly impossible, even with directions, for my stupid self to transform the central larger robot (I can't recall his name off the top of my head) into vehicle mode. Right now it's simply displayed as Devastator and will probably stay that way for a while.
Overall, it is a nice deal (5 TFs for 30 bucks), so I can't complain too much. I've still only ever seen it at that particular WM, though, so who knows when it will show up in larger numbers.
