Maybe its time to put a mint DD6 to the back of your collections and hope that it goes the same way as the DD5 and 2 and becomes a collectors pedal in the coming years,all though I dont know how many are out there and how many years it would take?
i mean is good to look for one mint and cheap i am sure you can still find them in store.but i don't know about resale on these there were alot produced.
