I have been reading Don Casey's book about repair, and upkeep of sailing
yachts. He recommends getting a sewing machine so that sails, covers,
dodgers, etc can be repaired, made etc by the boat owner.

I don't know anything about sewing machines.

Where would I get one? How much should one cost? What brands are good? Is
this something I can get on ebay?

Any help ?

Thanks,
