im pretty oldskool, i dont particulary use many effects and as long as the mixer has 2 channels, a strong fader and eq im happy, and a couple of extra mm on the faders is the least of my worries when it comes to a mixer, id rather that than a mixer like the 600 which, altho being fun to use, does feel like its going to snap in ur hands at any minute
ive used both many and it just always comes out on top for me definately, i cant wait to get one
i'd say the reason no ones gotten into parametic eq's on their mixers yet because its alot more complicated for your average dj mixer, those who really dont understand it are happy with a 3 band eq, altho you and others may wish to boost and reduce certain frequencies in the mix im guessing that not enough people have even thought about it enough for it to fruition into a viable idea never mind a product
mixers are a personal thing, you cant tell someone what to use and what not to use, go to your local music store with a few of ur fave records and get them to give you a few demonstrations before you part with any money
