well for this project dont worry about the cost as much as performance. if i was concerned about cost wouldnt have all 3 vxl's and wouldnt be gettin ready to install flextek arms in an emaxx.
Having done a jato conversion and owning a vxl rustler, I think the vxl rustler is a better platform for 2wd electric. I would suddest a crt.5 or hot bodies ligthning stadium 10. Both are better platforms than the jato, much more stable at higher speeds and better built IMO. I sold my jato, just did not like it.
