Want to build or buy an ARF? It will be hard to get everything new with that budget.

Consider used? Definitely some deals there...

Consider a Parkflyer? I hear the Firebird XL is interesting and certainly in your budget.

As for a beginning plane, there is a lot of advice that has already been said about it. Just do a search on beginner / beginning / first plane.

Sig Kadet LT-40 is a great one to start with too - both in kit form and in ARF, but budget will be an issue with any new plane by the time you add engine and radio...
