My father can get Keystone products and their radiators are supposed to carry a lifetime warranty. I don't know if he's ever gotten one of their radiators before, but their air conditioning condensers perform very well. I wanted to know if anybody had one, and what their opinions were. The more I think about it, I'm just not sure if I need to drop $500 on a be-cool when I never had overheating issues before. The Griffin is priced right but it doesn't seem to fit well. Anyway, if anybody has experience with the Keystones, let me know. Thanks.
