Get an internal, easier to set up.
I use a Cascade 400, and so far it's doing a good job starting the nitrogen cycle. It's got either a simple nozzle which just dumps out water, with an attachable air stone, or the spray nozzle which makes a big, noisy waterfall that I absolutely love to pieces.
Fluvals are very good, Eheims are supposedly good, but expensive.
It doesn't matter necessarily the brand, but the more expensive you go, the better quality the filter is, unfortunately. Make sure the filter pumps anywhere from double to five times the amount of water in the tank per hour. If you have a 50 gallon, it should pump 100 gallons per hour or even more for extra cleanliness. My filter cycles 110 gph, and I have a 55 gallon, with only 40 gallons in it.
