Exactly what EJ said. And it seems from what EJ posted that the EDG2 is 2.8k more than the EDG1 - I do not have a price yet. So this is how much it costs to go from composite to HDMI if you need it and not 6k as you posted. Considering what you want to achieve it is not that much since you now require another output in the DM switcher so you are already talking about an expensive system anyway. If you managed to sell the V15 or a number of V15s and the DM then upgrading them to the EDG2 is not that difficult. Or just do not send video to the touchpanel - they can live without that anyway.
