The only boat right now with full support is the 67 Road Runner from Ralph. The next would be the JAE 67 which is a good choice, however the kit has no instructions and I believe there is no cowling available. There are detailed instruction's from JAE for the 21 boat which will work for the build of the 67. There are many threads on IW for help which makes the JAE a good choice plus you can't beat the price. If you can find a used SGX or Crapshooter there is also great support on IW for them, the new ones just aren't around. Steven you said kit, so in that case the JAE is it. Ralph's boat is pre assembled and Starts at 1K. Good luck with your search.
