Hardcopys Original PlaneScape Boxed Sets, Etc.

I'm sorry I don't have the time to get into charactor anymore.
I'm Searching hard for HARD COPYS of original PlaneScape material pre/post WotC buy out.
Ebay isn't helpfull.
Also looking for most recient sets/books of DarkSun and the updated 2nd Edition materials.
I'm serious about this and not looking to re-sell.
Serious leads apreciated.
Please contact.
