These may not be top of the line Kayaks but I found mine to be functional and stable etc. I purchased mine at a Sam's club for around $250.00 in Grand Junction, Co. while coming back from Tahoe. My first trip was 21 miles on the Buffalo in Arkansas. I will say I found the seat to be a little flimsy for my 6' 220 lbs. but it was still there at the end of the day. If anything, I found the kayak itself to be a little heavy built. I do not understand these other folks comments concerning flex etc.
All and all I feel basically satisfied with my purchase for the money I paid. It was on clearance at Sam's, by the way, for that price.
