I see Costco in Kirkland is selling a 7 ft pontoon for $300. No brand name but frankly looks very good. I'm tempted to add to my collection...

Costco in spokane may have it as well. I agree with Raffpap, well worth it if you can stretch your budget. The only advantage of a U-tube (I have one) is they are easy and quick into the water and less storage hassle. A U-tube is a better shape if you have to go that route, vrs. a round tube. It's easier to kick.

A pontoon is the way to go if you can.
