go on ebay and you can find a 1 hp pump brand new that "looks" ok for a 100 bucks! it's tempting when you see these 300-500 dollar pumps and go "gulp". while it may be tempting, yeah, how long do you expect it to last? if you are hoping for 1 or 2 years then maybe a 100 dollar pump is the way to go..but if you want it to last 10, 15 years as many pumps do, with no worries..then i say spend some good bucks and get something with a good rep. when i think of pumping pressured water supplies for 8-12 hours a day and quite often working in hot conditions, a good pump is worth it's weight in gold. i also wonder how noisy these cheapies are.
