Eureka Boss Smart Vac Ultra 4870 CR Best Buy. This is the one that I bought. It's one of their best buys for an upright.
The others: Kenmore (Sears) Progressive with Direct Drive 35922 CR Best Buy
Hoover Tempo Widepath U5140-900 CR Best Buy
The Kenmore is actually rated higher than the Eureka, but it also costs twice as much. I didn't see myself needing the $150 difference.
