You'll need at least three technics 1200's, two
CDJ1000's, a 48 channel neve mixing console,
some sennheiser studio monitor headphones,
a couple of external fx rack units, compressors,
limiters, amps, eq's, loads of bassbins, an
MPC4000, a dual processor 1.25gHz G4
running pro Tools and a practice room
designed by a qualified acoustician. If you want
a good set up you'll have to be prepared to pay
though. A cheap setup like above will only get
you so far.
Oh, and i wouldn't bother getting any of that until
you've got at least 10 crates of vinyl.
I think American DJ do a package deal.
