I'm a big fan of an 1176/78 on just about anything...
the Focusrite Red is also a very versatile stereo comp. They just drastically dropped the prices on those (Focusrite)things , so I dunno if that means that the new ones are made differently, but the older ones kicked ass. They work well on the 2mix also, if you're into that sort of thing. They can be very transparent if you want 'em to be.
Here's a neato drum subgroup trick: bus everything but the overheads and room mics to a subgroup, and put the OH and room on another sub. This way, you can slam the fuck outta the first sub without having the cymbals pump like crazy. I find this technique to be very useful in many situations. Just watch out for phase! I was doing this once, and somehow one of the groups got phase reversed...it took me quite a bit of time to figure out why everything sounded strange. Ha.
Orange County made (makes??) some interesting boxes...super gritty sounding stuff, but they can be a neat character tool.
I find that if I'm mixing in the box, I use way more subs than I would if I were mixing analogue, just because it's real easy to set up...on an analogue console, you have to run tone through everything to make sure that the L&R of each bus is balanced, blah blah blah calibrate calibrate yada yada. The computer has spoiled me rotten. Sigh...
