I highly recommend the Midwest Aerostar 40. Our club was using 4 of these at one time as instruction planes. They fly great and the kit is really good. If you don't have the time to build, Falcon trading company imports the ARF version which I've heard is quite good also. For all around value, you can't beat the Hangar 9 Solo Sport. I won one of these at a raffle several years ago and have been instructing with it ever since. It has a street price of only a few dollars over $100. That's a pretty good deal.
