My boyfriend has an old boat, his grandfathers, in the basement and he'd love to refinish it so I was thinking of getting him a planer for Valentine's Day. I have no clue about power tools but he'a Craftsman man, almost every tool he owns is a Craftsman. I found 2 planers on the Sears website, Craftsman 3-1/4 in. Power Planer and Craftsman C3 19.2 volt Cordless Planer, it's all gibberish to me ....which planer would be more useful?
