I'm want to get into Ableton, but I never invest a lot of money in something unless I know I am going to continue using it, hence my current equipment. So, would it be better to get Ableton Live Intro and then upgrade to 8 later, or just go straight to 8? I heard that Ableton does not discount their upgrades, but I was unable to confirm that because Ableton requires that you already have a serial number to see update options. Anyway, any thoughts?
