I bought a used Ram 500 from a friend for $1000 and built a Balsa USA Enforcer modified for turbine. So I got my first turbine powered plane for under $2K. The Enforcer is fast and a very stable flier. It required extensive modifications, so you need to be an experienced builder. You can kit bash it into give it a variety of different looks. I've been flying it regularly for two seasons now.

The engine failed after about 120 flights. The Ram was difficult to start and more trouble than it was worth, so you have to be careful when buying a used turbine. It's now flying with an Artes Bee that I bought used on RCU for $1500. The Artes works flawlessly and I'm up to about 150 flights so far.

If you aren't an experienced builder and into kit bashing the best bet would be the A-10X from X-treme Jets as Avicom suggested. Buy a name brand turbine with a good reputatiion.
