Looking for source for old panel doors

I am putting in a doorway in a room, and i want to match the existing panel doors in the brownstone.

Anyone know of a source for old panel doors?

or

Anyone have a stack of old doors in their basement I can search thru and perhaps purchase one?

thx, eric .

there's a store that sells old doors and stuff. Store might be too formal a name for it...I don't think it has a cash register or anything. and sadly I can't remember what street it's on, so I'm not terribly helpful. but someone else must know it--it's right off Grand St, around the corner from Nu Yu salon and Dakar restaurant.

Hope that's helpful.

demolition depot on 125th st. ....also, try Brownstoner.com

or craigs list. or walking around on trash night. i constantly see old doors and wish i had a place for them
