Wanted - rear derailleur, seat post & crank

[Katie]

I am looking for a few components so I can finish rebuilding my old 'cross bike. I'm hoping to buy some of this stuff used & cheap!

Does anyone have any of the following lying around that they are willing to part with?
1. rear derailleur
2. seat post (27.2mm)
3. compact crank & bottom bracket (170mm arms)

Katie I have an older Easton 27.2 carbon post, if you are interested.
