If you want a really good skimmer, small footprint, I would recommend the Tunze models.
They are high end gear, but do come at a price... But well worth the money.
The Tunze 9010 or 9015 would probably work great for you.
Don't settle for cheap or mid stream, as I found out, you will eventually end up buying the better stuff, then need to sell off your mid range gear. Believe me, that has happened to me.
