I recently bought a J/22 for this purpose - fun daysailer. So I was heartened to see this (old) thread.
It already has the Schaefer roller furling installed. The tiller clutch looks like a nice solution - I put it on my list of things to consider once I get the boat. Also contemplating an electric motor vs. gas, but haven't reached any grand conclusions.
I do feel like I'm buying a race boat just to do a little casual sailing with, but man, everywhere I looked people rave about what a good-sailing and performing boat the J/22 is. Where I am has pretty light winds most of the time, so that was a consideration, too - need something light weight with decent sail area. Really looking forward to sailing it!
