I just heard about this company. You would recommend this and buy from them again. So many skimmers it's hard to narrow it down. Their look well built and sounds like a good pump.
I purchased the 181 within 24 hours I fell in love with it, then I found a used 201 upgraded to that and if a 251 popped up at the right price I'd buy it.
I bought a Warner Marine MF-121 which is essentially a Skimz that's been slightly modified by WM. It should be here by Monday and I'll let you know how I like it.
Most reviews of the Skimz and Warner Marine skimmers have been very favorable.
I've owned one for about 9 months. The 201 that I had was great. Never had any problems and started skimming the next day. I heard people had minor problems with the pumps so you might want to research some more on them.
