I agree with Curtis that the Bunn VPR airpot brewer would be a good way to go. Awhile back I was getting ready to set up better coffee gear for my workplace and found its cousin on Craigslist for $75. I cleaned it up and it was easy to use. The possible drawback is this isn't a brewer you'll use for light, acidic roasts. If I remember correctly it brews at about 190°F, but you can call them or call Bunn to find out. Mine had an adjustable thermostat, but it wasn't easy to get to, because these are really designed to be at a work break room.
What I WOULD do for a good cup of coffee!
