When I was looking for a fast something which is bigger than my MT10 and Hoss, I considered the E-Revo, but my Summit fills that (unique design) niche pretty well, plus I have the E-Maxx.
I looked a the Sledge, the Maxx, and a couple of the Arrma 6s models (almost jumped on one of the EXB rollers when they were on sale).
I decided on the Tekno MT410 for several reasons: it came in kit form, which I really like; it was priced at $369 at Tower, but once I added a JConcepts body, as a SS Club member, I got $75 off and free shipping, so it was really the best bargain for me; and I already had some Spektrum 6s electronics sitting around from my brief electric T-Maxx conversion.
