I've been researching this a lot recently...stuff that's pretty well thought of is... (in increasing $$$s):
Speck Xtramix (line only)
Chandler Mini TG (line only)
Aurora Audio 822 (line only)
Manley 16 x 2 (line and/or mic I think)
All the above are currently in production, for an older unit you could try the Amek BCII (Funky Junk (www.proaudioeurope.com
) in London normally have a couple for sale and they pop up on eBay from time to time), which I've heard good things about.
If you need really few inputs you could try something modular like Purple Audio or Tonelux.
Cyril at Raindirk Audio also builds custom rackmount mixers. Expensive but I don't doubt very high quality, here's the website - http://www.lntech.nildram.co.uk//
Good luck with it.
