We have a Fetco Extractor in the office. It makes fantastic coffee and has been trouble free since we installed it three years ago. We brew quite a bit of coffee, not quite cafe volumes but in a day we'll run 6 to 8 airpots and we use the water spout for heavy volume cupping days.
Cirqua makes a great water system that will protect your investment.
I used a lot of Bunn equipment in my former job. It was less expensive up front and nearly everyone could service it. However we switched to Fetco after having to continually replace parts on the Bunn brewers. The longterm cost of the bunns were higher. We had quite a few CBS series Fetcos without problems. This was ten years ago, so who knows if this is relevant today.
I do travel quite a bit and hit a lot of the better known shops out there, those who still use drip brewers tend to have Fetco. They're all cheap next to a Clover and all expensive next to a case of press pots.
