i use a MRC MR2 and i like it however my only complaint is the air intake is loud. it isnt a problem if its in a stand or plumbed to a basement/sump room though.
i agree, it is a very good idea to get an over-rated skimmer as Bcastle mentioned, as this is one of the most important things for your tank. the MR2 is rated 300 gallons where my tank is only 85+40 sump. it is also a very good idea to find a local reefing club in your area so you can pick up a used skimmer that would be 10x better then one you bought brand new for the same price. reading online reviews is also very smart.
to name a few good skimmers:
MRC, MTC, ASM, WM, BK, Octopus, ATB. honestly the majority of the skimmers from doctorfosters are garbage. dont get me wrong, some are decent but many arnt up to par.
and i have heard great things about the bubble kings but the cone skimmers, like this one for example: The New Jersey Reefers Club - K-2
make BKs look like honda civics IMO.
