I'm outfitting a new coffeeshop without breaking the bank and am looking for a good roaster. 5K-10K running Natural Gas. I've talked with the Ambex folks. Toper seems to be popular and I've seen some used DIEDRICHs and Primos. If you were opening a new shop and had to live with your choice for a few years while learning, what manufacturer and model would you choose? Which ones handle small batches for experimentation best?
