When you're comparing MP10 with MP1 remember MP10 comes with a trailer, roller and Spike. MP10 trailer MUCH better then the trailer that came with MP4 does anyone remember how much MP4 was? I think I got mine for $200 at Target and we still didn't get Roller with MP4. Also I don't understand why so many people have a hardon for diecast in figures. Sure MP1 was cool because he was loaded with diecast but after 10years all the paint on mine is all chipped all over him making him look really battle damaged. And the ONLY Binaltech I have (Meister) has peeling paint all over him as well. Not to mention my Soundwave's feet are all scratched up as from just standing on my desk.
