Only suggestion I can think of for you would be to build a trainer.
www.towerhobbies.com <---- They have lots of trainer kits to choose from. Then again you said you already have a trainer so you may not be interested in getting another, You can also look at the Sig Four Star, I have a 4* 60 but I have'nt started it yet. I have read alot here on RCU that it is an easy kit to build for begginer kit builders and the manual is very easy to comprehend, just like the manual for the LT-40 I built.

http://www2.towerhobbies.com/cgi-bin...?&I=LXFG16&P=0 ---- Sig 4* 60
http://www2.towerhobbies.com/cgi-bin...?&I=LXFG08&P=0 ----- Sig 4* 120
Just a few suggestions.
EDIT: ChuckW is right about the kit price range, My LT-40 kit and everything to finish it totaled over $500... but then again, I added a couple non-essentials.
