World Models SS 40 or the World Models T-34. Basically the same plane, very forgiving unintimidating first low wingers. Cheap, too...
4* is an excellent choice, although a little more pricey.
If you're looking for a taildragger, the Worle Models Skyraider MK II (?) is very inexpensive and a good flier, or a Sig Rascal .40 is a good choice, although a bit more expensive.
