Sh*te, that's a tough one.
All I can say matey is (when you've got the cash together), buy DJ Mag, and look through all the adverts in the back pages. Ring em all up and tell them the best prices you've been offered, they'll usually try to match or beat their competitors. Also ask em if they'll throw anything in free.
I got my DJM600 and 2 CDJ1000s from DJ Gear (Orange), they sorted me out a good price and threw in some leads and a (cheap) pair of headphones.
One thing I wasn't happy about at the time was that they didn't tell me the DJM600 wasn't in stock when I placed the order, and I had to wait a week - which when you're an impatient git like me, is a long time...
Also, I had to ring up 3 or 4 times to ask about the extended warranty.
Good luck!
