For the ammount of money you will spend on that CPR model,you could build/DIY an awsome one,twice the size under your main tank...
All you need is an overflow,a return pump(small and low power),and a cheep glass tank...
For lighting a 10 dollar flourescent light fixture from the hardware store,and a grow bulb or two is all you need...Total of a homemade 'fuge could be as low as 150 bucks...I'm sure the CPR is alot more than that,and nowhere near as good as a homebuilt is...
