Check out the Overstayer Stereo VCA ( the full rack unit, not their half-rack units).
Overstayer Recording Equipment - Stereo VCA Compressor
I bought mine a couple of years ago after running across huge positive reviews on Gearslutz and other sites....I mean, I don't think I read one bad comment.....and the price is great!
I was looking at other comps (API SSL) in the $2.5k range, and the Overstayer is under $1k, but will stand toe-to-toe with any of them.
Their other two half-rack comp units are also great (I have all three Overstayer models, though now they just sell the Stereo VCA and the FET half-rack)...the FET model being exceptional on drum tracks, but for the stereo bus, the Stereo VCA model just kills. It also includes an EQ section that can be taken in/out of the circuit. It's a basic low-end & high-end boost-only affair...but it can sound quite good, and in a pinch, take care of your post-comp EQ if you have no dedicated stereo-bus EQ unit.
The Stereo VCA is permanently hooked up to my console stereo bus....I have had ZERO disappointment with it.
I don't nuke with it, rather I just use it to tighten and punch up the mix, and then when I pull the mix back into my DAW, I only need to apply a touch of digital "limiting/maximizing" if I want more level.
