Flag,
The good thing about these separate licences is that you can buy only these licences, that you need. You don't have to buy all the stuff you do not use! I really wanted Flex. It's good tool with support and updates, but, the tool with OBD licence is 3+kEUR, then you have to pay for subscriptions every year. I am not so active in ECU remap business, so i'd go with flashers where i can buy 1-2-3 licences and it would cover 95% of my needs.
