I have an Eshopps S-120. It is actually my second one. The first one the pump died after 2 years. I replaced the first one with a reef octopus sro 1000int. Never got it to work very well so I got another S-120. It pulls great skim. However after doing more research I think I never had the reef octopus set up correctly so i'm going back to it. The eshopps is only a month old. If you are looking for a used one it should be on craigslist soon. I can't sell on here yet, not enough posts.
