The base price on the is $3,800. I noticed the seller is asking $2,500, but obviously less is more. It's capacity is .454 grams, so right at a pound.
Here is a quote from their site on the capability of the roaster, "An efficient coffee roaster provides the RoastMaster with the ability to adjust the time of roast, degree of roast, allow change in heat mediums (convective, conductive, and radiant heat), and the ability to speed up or slow down temperature ramp rates. Other roasters on the market do not provide the ability for all three."
I would tell you to at least go check it out and play with it if it is nearby. It seems like the seller, based on their CL post, would be fine with you stopping by to roast a 'test batch'.
