Looking for gently used tights.

I have posted this on the apparel thread too. So sorry for repeating myself, but I know not everyone ventures there.
I am looking for a pair of med cold wheather tights w/ chamois. I just thought maybe I should check. I would buy a new pair but i really don't need them here where I live. I just want them for this bike trip that I might not need them on either. So as you can see I just don't want to put the $ if I don't have to. You know starving artist type. Thanks!

Have you considered knee warmers. They might work in place of the tights and do come in handy at other times. I actually prefer them to my tights.
