for the 1800 lph of air and 38watts power useage of the alpha 250 paying $1200ish seems pretty crazy when you could go with a RLSS r10-i with 1800lph of air draw and 40watts power usage and a controllable pump for $749. Or the CSC 450 with 1680lph @ 52watts for $800. Or even JNS skimmer (which has very solid reviews on RC by Mojo (he is the USA version of Skimmer King) and many others.
I get paying for a name, but all three are solidly built skimmers with great power efficiency and big air draw.
Good luck with your purchase and lets see some pics and a review with whatever you get.
