get yourself an easy set up to start with
learn the basics first how to mix when to mix etc
get yourself a good book on how to do this
if your serious about taking it to the next level
then get what you want
i started on belt driven decks easier than direct to learn on
and once i got the hang of it i purchased numarks ttx1's
and got a fancy mixer i'm now also in possesion of about 2000 pieces of vinyl
good luck
