01327 301901 - Ask for Carl or Kev and tell them I sent ya (Ben). Should be good for a 50% discount..
Seriously though, they will sort you right out and are always there at the end of the phone if any help is needed..
RRP to go straight to Stage 2+ would be £599+VAT + the switch which are normally on some sort of offer (if not try the classifieds on here or Ebay). But you
may be able to get it a little cheaper hopefully..
