Makita 18v LXT Cordless Vacuum with battery and charger $50
At the Home Depot in Corsicana, TX I came across this vacuum for $50. The vac only is $79 on Amazon, and the kit is $169.
This has two dish washable filters and in my opinion better than the Dyson. You can use a larger battery for longer operation. Makita also sells an inline cyclone to keep things from hitting the filter which makes this incredible.
