Or more specifically, is there anything much wrong with the Barbieri one? It's on offer from an OBS, at about 1/2 the price of the other ones, and I'm wondering whether that's because it's not so good, or just a clearance issue. I know the job can be done with a toothbrush, but I'm really after some help on this - has anyone had any experience with the Barbieri chain bath, positive or negative?
