I'll further the suggestion of going with the Sig Kadet LT-40 for your next trainer. They're truly a joy to fly, and you can go with the ARF or the kit depending on how much time you want to devote to constructing your plane. The LT-40 has truly terrific flight characteristics, and you'll enjoy flying it long after you've advanced to more aerobatic aircraft. Sig's kit version is laser cut and is considered very easy to build. The ARF version has a terrific covering scheme and should stay looking brand new for a long time. The quality of covering on various SuperStar and HobbiStar ARFs I've seen has varied somewhat; I've seen club members vow never to buy another Hobbico product after their covering started peeling off in sheets. Those kinds of problems are rare though, and I myself was quite happy with my Nexstar's covering.
If you're looking for a fantastic deal that doesn't involve very much assembly, you should take a really good look at the Thunder Tiger Tiger Trainer MkII ARF from
http://thundertiger4u.com The Tiger Trainer Mk II is designed to be a "glueless" ARF that can be put together in less than an hour. Furthermore, the folks at
http://www.thundertiger4u.com have a combo package with the Tiger Trainer MkII and the very highly rated Thunder Tiger GP .42 motor both for $150.00 By coincidence, that is exactly enough of an order to qualify for free shipping. You could order the Trainer MkII and GP .42 combo, then put whatever radio you'd like in it.
The Futaba 6EXAS is certainly a fine radio, but don't overlook the new 6-channel JR Sport radio system available from Horizon Hobby. The JR Sport package includes a full flight pack and a 6-channel computer radio with 10 model memory all for $159.99. It's an awful lot of radio for that low of a price.
The Tiger Trainer MkII ARF w/ GP .42 combo combined with the JR Sport 6-channel radio package would give you a very high quality and easy-to-assemble trainer package that would stand out from all of the Avistars, Nexstars, Superstars, and Alphas at your local flying field. It would also be a great value for the investment you'd make.
Good luck!
