This is really not a post about opinions as to what hounds think works best so much as a hot tip on a find I have made (although, by all means, let the debate begin).
Anyway, those who are familiar with the Rabbit screwpull know that it sells for about $79. I just acquired a very serviceable knock-off for under $17.00, plus $6.00 shipping, from Walmart.com. It's called Arcosteel and, it is, indeed, a steal.
I don't think you can find a better corkscrew at this price.
