I would definitely look into buying one (supposed to come out mid-May)... if they used metric hardware. Their 1.9 MRC does, why not the 2.2?
I actually got to drive their MRC (completely stock) for about 30 minutes until they told me to give away the radio, and it was great. I have always wanted to build a crawler, but after actually driving one, I definitely will.
I always thought going slow would bore me... but I didn't realize I would enjoy driving it so much.
