I'm finally trusting my P3P and want to get some extra range on her when I need it. I was looking around and there are a bunch of different Windsurfers that are being sold. Money is tight lately, and I don't have access to a 3D printer. And honestly, if I build one, it's not going to be as smooth and nice looking as I would like. Are the ones being sold on Amazon for $20 the best bang for my buck? Anyone seeing any difference between copper and aluminum? I know as long as it reflects, it should work. Just seeing if anyone sees a difference.
