Don't know if any of those will have quite what you are looking for. There is another one, not Fisher Scientific, that I can't think of at the moment. Fisher probably has them, but in bulk only.

grin 41 cents a peice, or just over 82 bucks for 250 of them, without caps- those are five cents a pop if you need to buy them.
