Anyone own a Solar Bear heating system?

I want to buy a solar heater for my 24' AG pool. I've been looking at the different models out there and so far I like the Solar Bear model because it uses a single 4 x 20 panel instead of connecting two 2 x 20' units together and it has a built-in bypass valve. Does anyone own one of these and what do you think of it?

Thanks

Peter

I think if you have a choice of 2 20x2 vs 1 20x4, the 20x4 will win unless you have a configuration issue. Half the plumbing, same capacity.
