Numark 5000FX Mixer, €550 worth buying?

I thinkin of gettin a Numark 5000FX mixer, I found a site dat selling it www.musicstorekoeln.de/englisch/. Its goin for €550. Im very interseted in it as its got a nice crossfader for scratchin, a 30 sec sampler and effects. I dont know anybody dat uses tis mixer and I hav never used it. Does anybody think tis would be a good buy, as I want to use to it to scratch wit effects? Would I be better gettin a an all out scratch mixer and seperate fx unit, or for da price is tis a better deal?
