one of my hot water setups is the model that you are talking about. good machine so far.(367 hours) the only issues is that some of the accesories suck. from the start, the chem inj. couldnt draw out anything. easy fix was to buy a new one. put the extra money into it with good filters.
sure, some might say that you should go with this or that, but for the money its hard to beat what you want. once again, this pw or that pw, might be known for their customer service or what ever, but bottom line is that its a pw and they are easy to fix. if you dont feel comfortable doing it, take it to a local pw shop, and they will be able to take care of it for you.
