The boats were well made and very light, the bucket versions. They had the old Halkey-Roberts valves with the high center stem. These valves are a pain in the ass, they break easy because if you step on them you break the stem.
I would say if you pick up one fairly cheap, maybe $500-600, it would be worth it. I wouldn't pay much over that though. They are made of Hypalon material, so repairs are fairly easy. They are no longer in production. Hope this helps. Dan
