My personal opinion , like i said in the link Deanos provided. the turbo berlin is a great skimmer. Most of the time people just have their personal opinions on what they like better. Mine skimmed great and the noise wasn't really an issue- i had it running my 46, now its on my 150. Dialing it may be an issue beacuse of the knobs location on the pump, but i just left it at full.
up 2 u man, i personal think all skimmers r the same as long as they do wut they are suppose to. I mean the obvious exception is known crap like Skilters
