Just listed a bunch of the model kits I got about 10 years ago when I was trying to bolster my WST ranks. These are the Chinese knock offs from the official Kabaya ones (from what I can figure). The "larger" ones (Metroplex and Getaway) are great quality and definitely recommended, they snap together and stay together. I have some of the others that I'm keeping (Trypticon, Scorponok, PM Prime, Sixshot) which I've assembled and they're really neat. http://www.ebay.com/sch/rufustein/m.html
