Tuning a Mopar Computer

Where can a DRB be purchased from and do you have a part number of the item? Would you know around how much it would cost? Also, would you know the part number of the Snap On Scanner, could I purchase from Snap on directly, and approximate cost? Any help with these questions would be greatly appreciated. Thanks so much.

The DRB is the mopar hand held checker that the dealerships have. I would try Ebay or someplace like that. The snap on scanner I believe you purchase them directly from snap on..I sorry I do not know much about them...I have friends that have a DRB so I borrow it when I need to make the setting, I guess thats one good think about living in the detroit area.
