are you posting this from Hong Kong? now it is 1:45 am in Hong Kong. :decaf:
I guess you drank too much of your coffee ha ha ha
anyway, then, you came to right place. I am a green coffee bean exporter from Guatemala, so I have no idea about "reputable" roasting machines, but there are a lot of people here who might be able to help you.
good luck.
by the way, I will be in Hong Kong from June 11 to 13, staying at Charterhouse causeway bay, right next to the Time Square.
also, have you tried 18grams and coffee academics in hong kong island?
right by my hotel, new Coffee Academics just opened up (i think it is their second or third store in Hong Kong Island) and I can not wait to try it during my next trip.
