I know I'm not a regular on these forums, but thought I would weigh in. You can purchase Nomacorcs (1.5" straight) for $100/1000, or 0.10c/ea at Waterloo Container. Even after shipping up to Nova Scotia (and associated taxes), it was reasonable (0.145c/ea). They do offer the 1.75" as well for a little more. I had a pleasant experience dealing with them as well.
Part of the reason that I purchased Nomacorc is that I believe (please correct me if I'm wrong) they won't dry out like agglo/cork, so you don't have to be in a hurry to use them. I also believe them to be superior to agglo corks, and at this price, better value for my needs than natural cork.
