Fastfly,

My second plane was a Tower Hobbies Kaos 40 kit. It definitely moves quickly with a 46FX. Once you get real good on your trainer and if, and only if, you have an instructor willing to help then the Kaos is a great second plane. Since you want an ARF here are some in the $100 - $160 price range:

Tower Kaos ARF - $119
GP Big Stik 40 - $109
CG Tiger 40 - $159

Those should all give you a good rush when your ready!
