you basically want to stay with a straight cord wing type, not tapper
4*, contender, or even a sum'in extra.
i got my contender and ace4-40 both for under $100, built.
You might condiser building a kit becuase, eventaully you gonna have to
learn how to make repairs, if you build one you're have a better understanding.

A mustange is nice looking on the ground, but once to gets it up in the air, it's
a different ball game..you're going to have to really, really stay focus
becuase it's a lot harder to see.

They're also a little bit harder to take off, if your flying site is not totally perfect
or pave. Yes, retractes are nice to have, but you gotta makesure when it extends,
it extends forward enough of the wing so it won't easily nose tip during landing
or take off. Then you'll just spend time replacing props instead of flying.

You can go with a dura stick and learn how to land a brick.lol
Convert it to a tail dragger if you want.
I crashed one of mine many of times and just brush of the dirt and fly it again
and again. Good for doing touch and go, proceedure turns. The way i have set up
or extended cntrol surfaces, it get toss around enough.
