Best filter for a betta tank

[james..]

What would be the best filter for the job?

Note: Azoo/whisper filters are not really avaliable here for a reasonable price.

I live in Australia, so I can't.

I have a 5 gallon divided tank and I use a 50 wyatt visa-therm. It works great! I didn't get mine from a store though cause I thought it was a bit too expensive and I didn't have enough money on me at the time, so I go it from this guy that my bf is friends with (he works at a fish store and would get stuff in for much cheaper and he would bring it home), so I only got mine for $5.00!!! It is about $25.00 at your LFS.
