I think the 28's are the hardest to find. When I was checking OSO regularly, for some reason, I rarely saw 28's on there. On the West Coast, the 28 & 30 imo are ideal for the lakes and rivers out here. But still, trying to find a 28' anywhere is probably going to be hard. I don't think people let go of them. If they do, its a private party "I heard you're selling" kind of deal. Good luck with your search. I think the 28's and 30's are definitely bad ass boats.
