Just my view obviously...
Having made the jump to Ableton, I don't know why you'd want to complicate things with vinyl. If you're doing an Ableton set and you have time to mix in records then you're not doing enough live stuff.
Yes, of course, it's the sound that matters, most of the crowd don't give a shit, blah blah blah usual anti-chinstroking rant, yawn etc. But embracing technology means just that. If you're just using Ableton to replace record decks then you're missing a trick.
