They are exactly that. Incredibly cheap to operate, but a ton of fun. I can fly all I want essentially for the cost of gas. I've got nearly 500 hours of flight time in mine. I've flown it from Indiana to TX, TX to Oshkosh, and all over TX/OK/AR. I can't see why I would ever not want to own one. It is just a hoot to fly. Great short field performance, and overall an entirely different flying experience. Low and slow, you see things you never see otherwise. All kinds of animals...abandoned buildings...farmland...people. Everybody everywhere waves to the pilot in an open cockpit plane. Not sure why, but it seems to be a universal truth. I can't really explain why I like it so much...if it doesn't interest you, it probably never will, but I love it.
Any questions? Please ask. There is also a very active e-mail list with some very knowledgeable people. The cockpit is tight, I'm 6'0" and 170lbs, getting in the back is easy. The front is more of a pain. Once I'm in it is pretty comfortable, just with limited elbow room. I've flown it 9hrs in one day and had a ball, but I had a big grin at the end of the day.
I've given a good number of rides to people who had never flown in a GA plane...they've all walked away thrilled.

My trip home when I bought the plane...with only about 75 hours total flight time, and about 7 tailwheel hours:
