I used to work for UPS.

Good rates so long as you're not in the OS3 tier - then it can get expensive, even for ground.

DHL - Dunno if they've improved, I think they bought out Airborne Express for their national shipping, they used to be a primary International shipping company, their local rates weren't competative. Sounds like they are now, hopefully they fired all the Airborne Express drivers, they were all shitty.
