I have not heard good things about the "turtle filters". Though, I've never used one myself.
The Fluval internal filters are pretty good. I had a Fluval 1+ that's at least 10 years old (not in use for all that time, but in use for at least 5 years), and started it up after several years of storage, and it worked just fine!
You also might want to look on hang on tank (h.o.t.) or waterfall filters. With these, you have a bit more room for media (including biomedia). You may be able to find a good sized one for under $40.
Finally, check craigslist, kijiji, and the like, since sometimes you'll come across a great deal on a used filter.
