The majority of RTF's tend to have cheap electrics etc in them, if you go for an ARTF you'll probably end up with much better kit that you can the re-use on other planes later.
Depending on experience there are a load to choose from, personally I'd look at the Multiplex as good possible's, I've had the MiniMag and the Acromaster and am very tempted with the ParkMaster

which is due out about now, the Gemini's also meant to be a good plane and aerobatic but a bit more forgiving than the Acromaster.
If you prefer Balsa there are again a number of good choices, Extreme Flight Extra, Precision Aerobaitcs Katana and they're bring out an Extra about nowish or not quite so advanced HobbyZone and E-Flight have a number to choose from.
Might be an idea to say how advanced you are, what your looking for the plane to be able to do as well an if you prefer foamie or Balsa but hope some of those suggestions ahve been usefull.
