I have a 2000 Starcraft deck boat with a side console. There's no rail beside the console and only a small windshield that doesn't have a frame. I would like to have a detachable mirror , at least 78 sq in, that mounts to a permanently installed bracket on the console. The only one I've found is at PTM Edge and their price is $300.00. Surely there are other companies that have options. Does anyone have any suggestions?
