Replying to Buying m42 lenses?

I was hoping to purchase a few lenses on ebay, and then I noticed the shipping times. I found a few places to get a helios 44-2 (not at the best price, but still reasonable), that will deliver in about a week, but I wanted to buy a mir-1 also, and I am having trouble finding a place that will deliver before late november to mid december. does anyone here have any experience with purchasing either of these two, or other lenses and receiving them in a more reasonable amount of time?
