Craftsman ratcheting wrenches

Are they worth it? I think Sears is selling a 7-pc set for $99, down from $119, through Saturday. I think these are the unidirectional ratcheting ones, so you'd have to flip the wrench over to turn the opposite direction. The bidirectional ones seem pretty nice, but cost a lot more. Also the unidi's have I think 1 degree ratcheting versus the 3 degrees of the bidi's.

Anyhow, just wondering if anybody had much experience with them. Are they as tough as a regular closed-end wrench?
