I hear ya. I saw a 66 online that had a full set of back-clamping attachments for less than the cost of the attachments. Sometimes I browse categories -- that's how I found that lot. I've seen a picture of the corkscrew screwdriver, but never in real life. You see screwdrivers but they're usually not cheap -- like $5 each. They often got separated -- sometimes I see them in sewing baskets or "junk drawer" type lots.
