I want to do an accurate powered up Prime. I have everything worked out except for the feet. I would like to use a matrix APU like Optronix did for his, but that will cost me around the $200 US mark. I found a broken one for $12 but the prick wouldn't ship outside the US. Can anyone think of anything else to use? They don't have to be spot on I'll do as much modding as needed. I've looked at Gundams, Bionicles and stuff like that online but haven't found anything close. I'm not familiar with anything other than the movie line, would any other transformers do the job? The closest thing I have seen is a star wars AT-ST walker but the shape is all wrong and it doesn't look very sturdy, I'm hoping there's a better option. Hakka. Hakka.
