Djm 850 vs DN x1600 vs DB2
	
	
		So I'm looking for a stand alone mixer with traktor integration. These mixers from pioneer, denon, or a&h seem to fit the bill but I can't seem  to find major differences to justify the prices. The denon seems to be a bit of an underdog- nothing but rave reviews and built like a tank with a huge price difference? Has anyone used these mixers? The a&h looks awesome with its effects but I'm still undecided. The djm-850 seems like everything id ever need but again its way more money than the dnx1600.
Any thoughts or opinions? 
Cheers.
