Hi, hope this is the right place to ask a question about Durston rolling mills. I'm hoping to get the Combination mini 100 - I want to recycle my scrap silver and roll out my own sheet. Is this mill up to that task? And also, I've heard that without the 4:1 gearbox (like on the DRM100) they are really difficult to turn - is that true? Would love to hear from people who have these. Thanks in advance Sue X
