 Bob,
There is a plane that you can build that will cost you 9/10's of sweet 
bugger all - however it plans built.
The beauty of this plane (Vision) is that you can make parts as you can 
afford them.
I guess you already have instruments, engine etc.
Worth some consideration.
I'm working on a single rotary for the Light Sport Category (Vision).
Power requirements are between 115 and 125hp.
