We have a commercial Bunn at work and I'm happy with whatever coffee they buy to throw in that through the day.
I have a 12-cup Bunn pot at home, but only use it if I have company. Otherwise, I use the Keurig.
I'm happy with the quality of it, although I wish it were less expensive to run with commercial pods. My go-to these days is usually the plain red Krispy Creme(it use to be called Classic-they've recently renamed it and changed the taste a bit, although they claim the latter isn't true), but have used a fair few different medium roasts and like most of what I get out of it. Gevalia is good, as is 8 O'Clock(the latter, whether pre-ground or beans, has always been one of my go-tos in drip pots, so it was a natural choice for me in the Keurig). I found some dirt cheap generic branded pods at Rural King that were $8 or $9 for a box of 40, and they were surprisingly good but I don't make it to Rural King often enough to keep a regular supply of them.
My parents also use a Keurig daily. My mom usually drinks Krispy Kreme or Gevalia also, while my dad puts pre-ground Folgers in a reusable cup to make coffee-colored water. I'll put in a side note that I'm not an anti-Folgers snob-in fact it's what we generally have in the work pot and by volume I probably drink more Folgers than any other brand. I've found both the Folgers pre-made K-cups, and Folgers packed in a reusable K-cup, though, to be far too weak for my liking.
For the odd occasion that the big pot is down at work, I also have an old GE electric percolator that I keep in my office. I'll fire it up occasionally too because I'll get an notion that I want percolated coffee, and have introduced some other folks at work to the "wonders" of it.
Since there's been some discussion in this thread of Bunn coffee makers, I feel obligate to mention my user name, which refers to a signature product of the Illinois Watch Company of Springfield, Illinois. The Bunn Special grade(and the earlier Bunn) were named after Jacob Bunn, who was one of the founders of the Illinois Watch Company and also a law partner to Abraham Lincoln. The Bunn family stayed involved in industry around Springfield, with Jacob Bunn later co-founding the Sangamo Electric company, and a fair few years later another Bunn family member founding the Bunn-O-Matic corporation.
