15g Nano Column Tank. Skimmer Input

[wicked_chicken]

I've got a little 15g nano set up, and am looking for skimmer ideas. There's not much room inside the tank, so I have been looking at the Aquamaxx HOB 1.5 and RO Classics. I really want something with surface skimming built in, which I know the RO and Tunze 9004 has.

Any suggestions?

Tunze 9001. Great skimmer, no reason for anything more powerfull on a 15 gallon
