Any suggestions for a small hand-held cordless vacuum?

I have found that the Black and Decker models are getting worse and worse; shorter operating time; shorter battery death and shorter ability to really annoy me. It is a handy gadget. Have you used something you like? If so, what?

A mouse ate through a heavy towel, the plastic wrapping and 5 lbs. of ground corn kitty litter when I left the bag in the car trunk overnight. No outlets nearby. A dust buster was the solution, in theory.
