so tonight i went to wal mart to get some misc items and i was walkin by the auto section and saw a rotary tool for $10. it was a walmart brand but i think i might buy it cuz i want one. do you think it would be a waste to buy it? or should i just buy a dremel to be safe

WalMart has Black and Decker rotary tools for $25 (last time I checked). I'd spend a bit more for a name brand one IMO.

remember that walmart will return anything... walmart brand or dremel brand
