Hi Guys I'm new to these forums so i'm hoping some kind sole can point me in the right direction. I have a Lexicon DC2 that i am hoping to sell shortly. It has the old version software (V3). 1 - Can i still have the upgrade to V4 done & at what cost. 2 - Also will it be worth upgrading just to help sell this unit. 3 - What price to ask with V3 / V4, the unit is in as new condition with all the relevant paperwork, boxes etc. All help / advice will be much appreciated.
