I didn't like the F28C, but the 280FX is pretty nice ship to fly. VERY, I mean EXTREMELY, stable in flight. In fact, with the trim set right you can take your hands of the cyclic and change course by shifting your weight in the cabin (not recommended - just an observation). Auto's are relatively smooth, but it's a little different with that "boat-like" fuselage because it catches a lot of air.
Furthermore, the transmission was made from an old Chevy (I think) and the design hasn't changed much. One of the major CONs is that you have to send the transmission to the factory for any major maintenance or overhaul... they don't allow that job to be completed in the field.
Also, the lamiflex seems to be troublesome for some folks. That, plus the higher maintenance and the difficulty in getting a really good track and balance may lead you to other manufacturers. Anyway, it is a very stable platform and you can do cross-country's in the 280FX for days and days without killing your spine.
