Valuing used coffee equipment

We continue to receive requests to estimate the value of used coffee equipment from United Baristas Marketplace users.

It's been our position to facilitate market pricing by building United Baristas Marketplace, so offering estimations both

• risks distorting the establishment of market pricing, and
• is imprudent as we haven't inspected the equipment

Yet there is clearly demand for valuations.

How could we better provide estimates, or methodology to value used equipment?
