I used Discount Truck Rentals when I moved last time, and didn't have any complaints with the vehicle. I had been recommended to use "The Driving Force" but they had rented out all of their trucks at the time.
The big thing is to know how big of a truck you need - and how well you pack (the looser you pack, the more trips you will need).
