Ableton controllers: the evolution x-session is cheap and durable.
But... are you really, really that good at beatmatching? Cos Serato demands that you be able to mix. Ableton is much more forgiving.
Then again you can't spinback ableton. That's a huge downside.
You really need to try a controller with Live; since a) you already have it and b) all live users should be trying to add more performance to their mixes. You really can cut fast and mix with the x-session. I think it has a large measure of the immediacy of vinyl.
But you have to prepare your files, just like you have to learn your records.
Thing is, you'll mainly be getting grime files rather than dubstep 12s in the next couple of years, so you may as well make the switch now...
