I highly recommend Hood SeaFurl. the one on my boat is original from 1979 and has never had a problem. I took it apart to inspect, clean and service recently and all working parts were in great shape, I replaced the teflon bushings in the foil and put her right back up... Still working strong.
Whether you go with Hood or not one recommendation I can't stress enough is to get a type with interlocking foil sections. The type that butt together tend to seperate over time, some of the brands have now added a lock screws to keep them together but even so I've seen a couple of these seperate and tear the sail.
