I've had this same debate with myself many times. Minn flyer says it for me---it's a hobby, and I realized that I enjoy building almost as much as I do flying (note the "almost" part!). I am seriously considering a Carl Goldberg Ultimate kit, even though it has two wings. I figure at my building speed, I could make 15 cents an hour should I get a job building planes. Kind of like when I was a ski bum, no money in it, but I had the best "job" on the mountain!!
