If you're not against buying used, then the Aardvark Q10 or the Presonus Firepod would both fit the bill very nicely.
Aardvark is out of business, so the Q10's are selling for dirt cheap on ebay (I've seen them sell for a little over $200). Presonus has just recently discontinued the Firepod, so the price is a little more than the Q10 (the lowest buy now price is currently $325).
Both units offer 8 inputs, 8 mic preamps, and 10 outputs.
I have the Q10 and it works very well!
