how much are you lookin to spend?
the best i found by far is the rainbow!
dyson’s just suck ass, they suck but the brush design on it sucks but great advertising campaign though.
kirby’s are good they are the old faithful of the cottenhead crowd, you can pick one at super flea cheap.
if you are thinking cheap go anywhere they are at everystore eureka, hoover, you name it, its out there. i have a eureka with the hepa paid $75.00 at home depot on clearence. works good except you have to clean it the filters and empty the cylinder after every use.
