The Rane EQ are available every day for under $100 on eBay. I suspect the Speck units are much more expensive.
I looked at the Speck unit. This is a parametric EQ, which is a different animal than the Rane mentioned above.
I owned a Rane PE17, which is a 5-band parametric. It is independently adjustable by band, and has overlap capability.
For me, knob twiddling gave me no visual cue, so I replaced it with an interpolating graphic type EQ.
