Help me choose birthday skimmer!

LOL.

SO... I'm torn. I like the BM Curve 7 skimmer, but it is rated for 185-240 gallons, meaning that it might be a little big..... Now i've read a lot on "over skimming" and i'm not sure what to think of it. This skimmer could be good in case he decides to upgrade (which he has done twice already).

I also like the Curve 5, but it only goes up to 140 gallons.

The BM NAC7 is awesome, but reefsupplies dosn't carry that model, and I was hoping to use this website for the first time to try them out.

Like i said, the total water volume is about 120 gallons. The display is about 50 gallons.
