Out of the three the Bridgies are probably the more populous, followed by Atlas, then the others. I tend to look at parts availability for a machine more than anything. I would hate to spend a pile on a machine that breaks and has no replacement parts available. So I do a thourough search to see if parts are readilly available from multiple sources before I make a buying decision. Not having any real experience with anything other than a BP clone I cant even begin to speak for the quality of any of the choices. Smooth operation, no slop, no visible wear or damage and available parts is how I would decide if I had three to choose from. Hope this helps...
