I've been thinking about buying me a table saw...an a belt sander I've foud both on a local internet store, and a fantaistic promotion, where you buy both with low price together.....Ah, free shipping!! But I've never worked with a beltsander before....sooooo I need to know how much does it help on a workshop. Can I shape wood with it? does it replace some of the annoying manual sanding work? The belt lasts about how much time with frequent use? In resume....is it worth? My tools are: Eletric drill(manual)...not table, jigsaw, dremmel, and a weak table grinder I already thank for all the help!!
