This is the one I'm looking at now. It has a useful load of 1,250 lbs and cruises about 185 mph.
Unfortunately it is about 3.5 times the price of the 177RG, and because of insurance requirements, I probably couldn't get a loan if I can't insure it, so... it'll be end of the year at the earliest (if ever).
Stinson would make a good hobby plane or weekend puddlejumper, but I'd rather get a Aviat Huskey if that was what I was looking at.
