Tunze would be first choice. CS220 would be my second choice.
Don't know why so many people knock the Superskimmers (except the 65 - that one is kinda crappy)... maybe because alot of people who have them use them as HOBs - and HOBs, by nature, are usually more "finicky" than in-sump skimmers?
Have a CS220 in-sump for my 125 (160g total water volume) and it has never overflowed or given me any trouble...consistent skimmate production (and I run it "dry") and almost never needs any adjustments... just 'plug & play'...
But the Tunze is a better skimmer overall, IMO, just more $$$
