I got a Field & Stream model last year for my b-day. It's kinda u-shaped but you sit higher in it than a round one. I didn't fish much last year so I only used it five or six times. Worked great though. I don't know how it compares to other models but it was inexpensive...about $90.00 from Costco. I saw the same one in Bass Pro Shops catalog for $149.00. It's light weight (about 9 lbs.) and comes with a backpack like bag. Takes about 4 min. to inflate. Good luck. Jer
