The Ryobe dust buster is the most incredaible thing out there. Infact, almost anything I have purchase that is this brand is nothing but amazing.  The ultra slim batterys you can charge up and use on my ryobe product. THe only problem is that you can only really find it ay home depot. lowes does not sell it.  But, its worth going to home depot. also, did you know you can use lowes cupons at home depot? Its pretty amazing what roybe can do so if you are looking for any type of tool i would totatally go with ryobe.  My boyfriend got me hooked to it.  He is mr fix up but i love using the dust...
