Reply to Recommend a mixer

Hello everyone, I'm planning to buy some cdj's (prob 850's) and I need advice on the mixer

I've looked at pioneers so far, but am not impressed by the 350... There are not many effects or filter knobs

The djm400 looks nice, but is it worth it? It has nice effects but is old technology

The others I'm looking at are the djm700, but it is also old and I really don't need four channels. This leaves me with the djm-t1... Can it be used by itself without traktor, because I'm trying to get away from a laptop?

Any other cool mixers I should check out? The top of the line 4channel mixers are out of my price range and are way more than i need.

Important features for me are filters and delay sound. I like the t3 delay in traktor

Thanks!
