Not much else really. What you are asking for really doesn't exist. Anything in that price range is basically going to be a Mackie, which is not really that bad. Great, or for that matter even decent mic pres will not be on the menu.
Good pres can often run close to $1500 (or more!) apiece!
A real recording console is;
1. Very large, needs a lot of "real estate" to keep. 2. Very heavy.
3. Expensive to keep maintained unless you can perform the maintenance yourself.
This is why so many people (and even pro studios) are turning to DAWs and doing their mixing in the computer.. Aside from all the benefits of random access, editing, automation of all parameters in a mix, full recall of mixes, they can get by with an inexpensive mixer to handle headphone cues and monitoring chores and keep the real mix "in the box". Then they will purchase, as they can afford, great mics, mic pres and front end gear like compressors and Eq’s.
My feeling is that there are a lot of small mixers that are more expensive and sound a bit better than your garden variety Mackie, like the Midas and the Allen Heaths ... but in practical use, the improvements they yield may not be as significant than if you were to follow the route I suggest.
As in all things, in audio you only get what you pay for. Yes, there are some small improvements with the Midas and the AH boards over the Mackie types but I submit that you would get better results by experimenting with mic placement and selection, tuning up your performances and working on squeezing out a better mix out of something like a 1604 ... they really aren't as bad as many of us make them out to be and any benefit you may receive from using a more expensive small format mixer really will be pretty negligible.
