I've had the cordless dustbusters, corded dirt devil handhelds, and a electrolux pronto 2 in 1.
My current favorite is an older corded Black & Decker Collector I found at a yard sale a few months back, it's bigger than a dustbuster and surprisingly very powerful. They had 2 of them, and I'm still kicking myself that I didn't get the other one as well, it's really a neat little vacuum.
