Well first of all, you are going to need more software like Ableton (basically a program that saves the tempo WITH the recording because there are no tempo editing facilities in reason's samplers). I would sugguest ableton becuase reason and ableton both run in sync (as one program) using ReWire and it's really easy to use. As for the hardware that's a matter of personal opinion, just get the best you can afford, or if you have a particular piece of equipment that you like from a particular brand, buy that brand! Sony and pioneer usually work for me and i haven't been dissapointed yet.
I'm so thankful for all the help i recieved when i was starting out clueless. And now i want to pass it on. It really is a beautiful online community we producers have.
