I'd really like to add a couple of solar heating panels to my pool. I've been looking around at different brands and sources and it is really tempting to try out some of the $89 panels, but I'm guessing I'll get what I pay for there. Looking at ebay when I look at fafco or heliocol panels, they are about 3 times that cost. Should I just suck it up and pay more? Or am I missing a good deal somewhere?
