Reply to Is the CDJ-900 Worth the dough

well i wish i could say it was one simple question but its more like one big complicated one, my dj buddy is finaly going all out on a setup, he started out using ableton with his apc 40 but wants to more onto a more traditional 2 deck feel of a setup, im pretty sure he has settled on Xone:22 and Audio 2 DJ, wich i helped him choose and i believe are great choices, and the one area where i know he was having alot of trouble deciding wich way he wanted to go with control as far as controlling 2 decks in traktor, potentially to 4 if he were to get a new soundcard and mixer, anyway, he's saying to me that he is pretty set on getting a pair of cdj 900's for $2100 with tax, in my opinion this is very unessesarry, in my mind the reason why the value of the cdj 900 is so high is because of a few main things, 1. the precision jog wheel, 2. lcd screen with colour and wav display, disk drive with mp3 readability and sd and usb drive capability,and maybe high quality sound card and usb port are up there but i dont believe there worth that much, the buttons, are they really that great, because the count vs the 400 istn a significant gain at all, so if you get where im coming from as a pure midi controller in my opinion the cdj 900 is not that amazing, personally, i believe something like the otus or otus raw wich is for preorder on djdeals.com would be a much better decision, both feature dual channel soundcards, and dual deck functionality, alowing him to use them for decks a and b only, or potentially A,C and B,D , opinions/sugestions/idea's/thoughts appreicated, i just dont want my buddy to spend way more than nesesarry and also make sure im not the only one that believes it
