Depends on if you're planning on having traditional vinyl as well.
If not then you're quite right: CD decks will take up less room.
That said, if you're planning on phasing out vinyl completely then I'd consider Ableton over anything else.
erm i dont really like ableton dude, tho i can see why others like it.
i just fancy one nice cd deck really.
things arent happening much for me anyway, my agent hasn't rang for days.
