Steven - where were you 2 weeks ago!! I just bought a Mad River Canoe and looked for a while for a folding version and nothing I found could stack up.
The biggest issue I came up against was weight capacity restrictions. A standard 16' canoe can usually hold close to 1000 lbs. More than enough for two people or more and lots of gear. But most of the folding or inflatables I saw were in the 500 lb max range - barely adequate in my opinion.
