Reply to Multi Channel Mixer w/ Filter Knob?

I was just wondering if there are any Multi Channel Mixers especially a 4 channel mixer that has a filter knob or an effect bank that acts like a filter knob.

example. Filter knob in the EQ section of the VCI-100.

I assume that there are but whats the cheapest?

Here's the story: I'm changing my set up from a vci-100 to a turntable, 4 channel mixer, and a kontrol x1. I enjoyed the convenience of the filter knob on the vci-100 and would like to have that for my new set-up. Plus I'm a bit broke hence the cheeper solution. I've played with a behringer djx750 but that doesn't really get the job done.

Thanks!
