I got my sunstreaker/sideswipe and powerglide CHMS model kits. I have to say these are fun to put together and hasbro is definitely missing a market with theses. The extra heads and hands make these sets. The choice of colors? Do whatever you want with them!... I am assembling a clampdown, deep cover, punch, and wildrider. These are just wonderful toys and I love putting the models together. Could the screws and pins come with an instruction set? Sure. And one of my sets did come with a small ring that did not completely form in the molding stage, but man these things kick ass hands down. Hasbro should pick four molds a year or so, and offer them in 6-8 colors. Put them in model stores or on the club site. I have big love for these things. I wish Hasbro would do this. They are missing out. A great example would be Windcharger. Offer him in red blue white black and maybe silver, green, purple, and yellow sell them in kit form for 10-15 bucks??? MAN!!!
