While I'm positive you know that, don't make the mistake of limiting Ableton to electronic music - it has obvious strengths in that department, but there's really no limit to the genre and style of what can be done with DAWs like Live, Logic and Co.
By the way, if Ableton remains too expensive for your taste, there's always Bitwig, which isn't quite as mature and has a much smaller, but growing community, yet it's very similar to Ableton's approach to music production.
