My favorite brewers that I have used in the past have been Fetco. Fetco brewers are not cheap, but they are built like tanks. If you are interested in air pots, I recommend the 2030 model. If you want to brew larger amounts of coffee I might recommend the 5000 series. Unless you are planning on brewing large amounts of coffee, I think the 2000 series should be big enough for most small to mid sized shops. One complaint with larger coffee holding tanks is that the coffee does not stay as hot as it would if it was in an air pot or caraf.
