Personally, I find that a good ole Screwpull and an Ah-So (the one with 2 prongs) - the one I use depends upon the cork, generally get the job done better than anything else.

I have a Rabbit, but I find the Screwpull is better, because it removes the cork more slowly and gently than the lever action of the Rabitt enables.

The Ah-So (especially one with a plastic handle) has the advantage of going through airport security without a hitch in a carry-on, whereas I have had problems with others having a helix.

If I lived near where Cordelli was, I'd pick up 4 of those Ecko Ah-So units for a buck in a New York minute.
