Aluminum boat brands are often regional, not sold nation wide. Some more common aluminum brands are DuraCraft, Lowe, Lund, G3, Smoker Craft, and Tracker Pro. But there is no guarantee that all of these will have a dealer near you. The regional brands can also be very good quality, should not be ignored.
14' will be really small for a larger body of water. In boats this light weight every 6 inches in length makes a difference in chop (don't cheat yourself on length).
