From $100 to over $5,000 Bunn makers are made to fit every budget.
When you search to find a professional Bunn coffee machine for a restaurant you should consider something like Bunn 20500.
0001 High Volume Coffee System - U3 6-Gallon Coffee Urn 120-240 Volt (around $3,500) or for a better looking machine, the BUNN 36500.
0038 LCR-2 Portion Control 1/8 Inch LIQUI BOX QCD-2 Liquid Coffee Refrigerated Dispenser is recommended (around $4,400).
As said, it all depends on your budget.
The Bunn maker will meet you where you are and allow you to bring a top quality coffee machine into your own kitchen.
So many people are spending their top dollar on drinking their daily coffee's at a local Starbucks.
I say, stop for one month your Starbucks fund and save to get your own Bunn maker, which gives you a far better taste and quality.
If your search requires a less "professional" machine, you can try the BUNN NHBX-W Contemporary 10-Cup Coffee Maker for around $150 or a more serious machine like Bunn 33200 Thermal Coffee Brewer - VPR-TC.
Bunn coffee makers are found at best prices online as you can get them directly from the dealership offering special deals and discounts.
A friend of mind always mentions how shocked he is that you can actually get a better price online then what he buys (wholesale) to stock his store with items.
Many business owners these days know the rule is: if you can't afford it, go online! Bunn makers are also available at local stores like Target and Bed Bath & Beyond, but the variety is limited and prices are retail.
