Protein Skimmer?

I use a Lifereef 24'' TALL skimmer under my stand.Hands down the best skimmer I ever used including some 5 foot skimmer I had in the early 90's.Practically maintenance free,self cleaning venturi which is no big deal unless people like cleaning out clogged venturis.All I do is empty the collection cup,no hiccups or loss of air going into the skimmer chamber for over 9 months now.
Hello All - Does anybody have that Deltec MCE 600 for hanging on the tank? If so, please share your comments; and what about noise output and maintenance? I know, I know it is expensive but I might try for it. Thanks.....
