I've got a an advanced elements convertible kayak, the second one here
inflatable kayak reviews I recommend it because it is much more sturdy then many of the other inflatables. It has built in support which makes it perform almost as well as a normal kayak. Plus, it can fold up and deflate which makes it east to transport. I would stay away from the super cheap ones because they puncture easier and because they can be a huge pain to maneuver sometimes.
Anyways, that's just my opinion, got any updates? have you made a decision yet?
