I asked someone from Melco that called me on another issue as to how you rated a tech on-site...and found that now they SEND a tech for all multi machine installations....also learned I already HAVE the Amaya Flex so I can add another head without buying program/dongle upgrade... so the search is on! Refurbished through Melco is $8500 per....but if I find one considerably less than that we'll give it serious thought...but must be close enough to pick up-freight is outrageous and tearing it down to ship could damage it...
