I love my fluval canister filters!! They are the shiznit!!!

You should got with the 205 model (110GPH).
You can get one for about $100 dollars of of ebay:

But for about the same price you can get a fluval 405 (350GPH) of ebay:

I actually just bought the 405 from the same guy. They usually cost twice as much.

And as for over powering filters.. I have a the Fluval FX5 on my 75 gallon tank. The FX5 is rated for an aquarium up to 400G!! And that is not to much filter for my 75G. So I'm pretty sure you could go with the 405. That way if you decided to upgrade tanks you could keep the filter.
