I have preached this very idea here for a long time. When considering buying a machine, consumables and spare parts are a BIG consideration. Even with clones and relabeled machines. They can be called "Old Sparky" on the label, and if they use Lincoln or Miller or Hobart consumables, then you just jog on down to the store and buy them. Even the Borgs have tips and other consumables now for the major colors. Get one of the Fujimatsosuki's, and you won't have the same luck, and your machine will spend more time sitting there instead of welding.
Even if you DID save big bucks when you bought it. I suggest that anyone who buys a cheap welding machine insist on a good carrying handle. That way, it will always make a good boat anchor.
