I'd go to a store and see if they are selling any display or floor models. I'd try to get one without a bag so it is cheaper to run. A vacuum either works or it doesn't and I see no need to buy anything over 100$. I used my Mom's cheapo 60$ dust devil and a hundreds of dollars miele and they both got the job done, it seems like manufacturers are having an arms race. The major concern is how easily to use the machine is and if it can get into tight spaces. You might be able to buy one that is refurbed or used for cheap. I don't think the used vacuum market could be too hot, but hell if I know. I want to get a easy to maneuver vacuum for stairs and under furniture myself, but that isn't a typical purchase.
