I have a penguin biowheel (330) that I got second hand on craigslist. I have no idea how old it is but it's been running for 6 months and despite looking like its been heavily abused still runs like a champ. Although I will say my tank is only about 60% stocked.
This is the new version.
If you're on a tight budget I would check into craigslist. So many people get aquariums and end up hating them and unload them for cheap. It's one of those things like exercise equipment that so many just want to get rid of. I got that filter, a 55 long, a stand, some tubing, magnet cleaners all for $40.
