I am looking at a DW 2005 custom 6 piece kit. it is purple clear-coat (maybe stain coat) (maple I think). It comes with hardware including a DW 5000 double bass drum peddle with a case. It has virtually never been used. it still has the original heads, (all the heads need replaced) and they are in SNK hard cases. It comes with three DW cymbal stands and DW hi-hat stand. The Old-timer that owns it does not know the value of it and neither do I. What would be a reasonable cash offer? How much are they worth?
