Good corkscrew

Whats a good Corkscrew that some of you guys use? I have an older cheapy POS. Pulled the cork in two on a bottle I opened the other night. I was lucky enough to be able to get the rest out without it dropping down into the bottle. Looking for something not too expensive, and that will damage the cork as little as possible. Thinking of collecting my corks like I do my Cigar Bands.
