I hear ya on cash. Might want to check out an SWC 160 cone skimmer though.
Its pretty cheap, and an awesome skimmer. Still $250 though, but a great price for what you get...
Its a great skimmer with a very nice sized footprint.
If you end up getting a cheap skimmer, I'd check out a few good ones that you could upgrade to so you make sure you have enough room in your sump to hold them.
I had a cheap skimmer and it just wasn't doing it, so I picked one of these 160's up. If you end up stopping by you can check it out.
