I have used Bunn in the past but now I have switched to a few Curtis G3 airpot brewers. I'm really impressed with the consistent brew temp, pre-infusion and it's shower/pulse head. The airpots do not in my opinion keep the coffee hot enough after about 120 minutes but for me that's not a problem since I never have coffee that sits that long. They are also more money than other comm. brewers but well worth it because of the quality. I'd also look at Capresso products. I have an M500 at home and it brews a great pot! They don't have the look of a commercial machine but they are built as one. The Capresso's thermal server lid is a bit of a bad design, if I'm not careful when I pour I usually end up with coffee on the counter.
