ive been waiting for someone eles to reply.
you know what i think about them mate.

It all depends on what you wanna do with it and how much you wanna spend.

CDJ 100 -
Advantages- Excelent little peice of equipment. 3 effects (jet, wah, zip)
you can use the ZIP effect to give the impresion that you've just pushed the Stop button like on the 1210. the other two effects should be pritty obvious to you.
Disadvantages- You cant set "CUE POINTS" on the tracks of a CD. (basicaly its like setting a starting point to mix from on each track. You can have something like 10 CUE POINTS per track. On the other CD decks they have a SCROLL button so that you can jump to verious CUE POINTS making it easyier then have to set each cue point again after the CD player has been switched off.
It doesnt have the Shock Memory (some have 16 seconds shcok memory)
It doesnt have a loop fucntion (this isnt important, but its a nice feature)

Its Worth the £250 asking price.

CDJ 500 -
There's no way on earth this is worth the £495 asking price.
It hasnt even got front loading.
Ok so it got loop function, but big deal!! you'd be better off with the 100.

CDJ 800 -
Virtualy the same price as the 500 @ £499, your better off with this as it has got loop function.


in my opinion if you've got £500 get the "CDJ 800"
if you dont wanna go that high get the "CDJ 100"

there is a big price differance there.

The CDJ 1000 doesnt jump what so ever, ive shook it and bounced it on my bed. Im assuming the 800 will be the same.
The 100 might jump a bit i dunno. you said it sounded like one of them where jumping on sharkeys set @ north.

get yourself to a shop that sells them and ask them if you can try them out, that is exactly what i did.

ill ask dava if he wants to sell his.

im fed up typing this now. dont even bother with Numark OR Denon

Pioneer are the Technics of CDJ's as far as im concerned.
