Another great trainer is the Aeroscout 1.1!
Its a "pusher", which means the prop is not in the front. Much lesser chance of prop damage on bad landings/take-offs. It comes with flight stabilization, the RTR is only $200. Another cool thing about this model is that you could remove the landing gears and belly land on grass, and take off via hand launch. So, no need for a smooth, long runway. You could also get skis for landing gear, for flying during the winter.
The problem with small, is that you are very dependent on wind conditions. However, I started out with this micro, and I can tell you it works great and can take a beating! As a matter of fact, my original is still intact. It also comes with flight stabilization.
