I'd go with a used Avon, Sotar, Hyside, NRS, take care of it, then sell it for what you paid for it 5-8 years later, someone compared ford/chevy/Hyundai, like a Chevy truck aforementioned boats hold their value. If you're going to roll it after each trip go with Hypalon for sure. Seems to me PVC and cold air don't go well together, here in the mountains Dec,Jan,Feb,March are cold on brittle material outside in deep freeze.
