Wow Ken -- you are wearing me down with sheer weight of words []

I respect your opinion -- but in part, I don't agree with it. I also don't want to get into a pi$$ing contest with you -- there is too much respect to do that.

However, IMO the four best trainers out there are the Nexstar, the LT-40, the Hobbico Superstar & the Hobbico Avistar -- not necessarily in that order -- it depends on the individual student(s).

The Nexstar covers a much wider range of natural abilities than the other three, & that is its great value. I don't think that it limits a student's ability in any way (AFS excepted), it progressively enhances that ability if used as intended.
