I bought a rolling mill off of ebay...what a piece of junk. The ends of the rollers cracked. The company wouldn't warranty it, felt I didn't know what I was doing. The seller was embarrassed and did cover it. I ended up buying a Durston from Rio Grande. They have several price ranges, mine was a bit more because I wanted a 3" wide flat, for buckles. It also rolls into squar(ish) shapes and wire can be drawn down from there. It is geared so isn't as beastly as the one my old boss had.
You get what you pay for!
When I was setting up my trade shop, I really wanted one badly as it was a PITA having to do all my milling at the retail store I wasnt in a hurry so I kept my eye out for a nice machine. Ultimately I got extremely luvky and found a local auction that was selling a jewelers estate. I was able to get a motorized combination Cavallin Italian made mill at a fraction the cost of new. The tool suppliers have demo and used mills quite often. I would check with them regularly and let them know what you are looking to buy.
Lastly buy quality like Durston or Cavallin They will last several life times if taken care of properly.
Thanks to all. I was afraid of the quality of some of the ebay listings so just decided it was better to spend a little more and bought a 70 mm Durston
from Otto Frieis .
You will be happy with that! Unfortunately, having not bought a piece of ####, you won't know just how happy you should be! LOL It will serve you well and last for years.
