well i just ordered my ES5-2 from premium aquatics. acording to their site they have four left.
i would like to have waited for some reviews on it before buying it but i guess this time i'm your guina pig, so i'll post back here when i get it and let u know how its working for me.
in response to lunchbucket:
i was considering a CS6-1 but decided against it for 2 reasons. first, cost. i know to some the $100 diffrence isn't that much, but my reef definately runs on a limited budget. and seccond, space! i'm using an old wet/dry i picked up for 50 bucks as my sump, and the CS6-1's footprint is about an inch too big to fit in there.
