If you are intent on collecting corks, stay away from Ah-so or "Butler's Thief" styke cork removers. They scuff up the sides. The syringe style generally work well on newer vintage wines. I'd be shy on a 60's Burgundy with it.
Personally, my favorite cork screw is a quality T Pull. The waiters style work well, but I do not like the step to pull the cork and just use the waiters like a T Pull.
Here's some quality waiters style
