Hmm....don't go with low quality on the pump thing....that's probably the most important thing in your setup...
I've got the Eheim 1048, it's really great......and my impression is, that it's really stable.....and good quality....
But if ya look here, there might be a couple of "cheap" pumps....

EDIT: The Aquabee 500 is very cool also, and it's dimensions are quite small for such a powerfull pump, not so big like the Eheims...one of my friends have that Aquabee pump, and he likes it very much, it's also silent
