hi bailz, depends on condition of the door obviously. for a rust free complete door, glass,reg,handles, and everything i dunno havent really thought about it. reproduction door shells are around the 150+postage to wa so i spose for a great condition door maybe a little over 200.
if you have one why not post up condition and what kind of figure youd want to part with it.
i do have a door that is in poor condition so i have all the parts needed for a shell. and numerous other spares for it also

cheers
