Check out the world models 120 http://www.theworldmodels.com/para/p...airplaneid=165
The problem was the covering was cheap, but it was one of the best pattern planes I've flown (under $300).
Search "Spot on 120" here and google and you will find a lot of info. I used a YS110 in mine, but a OS120 or similar would be better. This plane as adjustable incidence, something you don't find in many planes under $750. It's worth a look.
