Hi - I'm about to rent a drum sander and an edge sander and a floor buffer w/grit screen to refinish my wood floors. I'm just taking off the very dark finish - no bits of linoleum stuck to wood or anything like that. I'm hesitating because I saw tonight in Lowe's a rentable floor "pad" sander. Supposed to be much easier to control - and that part is attractive to me - having no actual experience doing this before - only reading up on the subject. Any hope to get away w/ a reasonable sanding using only this floor 'pad' sander?
