The Caprio and J-325 in my opinion are pretty pathetic units performance wise.
I would recommend the Sweetwater Bahia if you are looking at a larger tub or a Tiger River Bengal at the same size as both of those units. The Bahia or the Bengal should be around the same price range as the Caprio or J-325.
Also, you will save some money on the Caprio or the Bengal if you run those units 110V.
