At http://www.dcpoliticalreport.com/, they have a listing of 17 polling firms final predictions on the 2010 congressional (House) elections.
Republicans had a 6074% margin over Democrats (BallotAccessNews), and here is what the firms predicted (margin of Republican victory)
The Good:

Tarrance 6
Reasonable:
DCJ Research 9
Zogby 5
Absurd:
