I just got my system about a week ago, now putting together the plan for installing it. It is a Chinese Siton three axis DRO with glass scales, and that price includes the shipping via UPS. Paid for by PayPal. No worries at all about the order, came as scheduled and the boxes were pristine on arrival. Might as well had come from a USA seller, seamless. If you do some studying, you will find that glass scales have higher resolution (.0002" standard, .00004" for $18 per scale more) than the AccuRemote and iGaging types. The cables are metal clad, the connectors are metal and screwed to the scales and readout, and there is no inaccuracy accumulation with length of travel. The kit comes with the installation hardware and protective covers for the scales. The scales are custom made for each order, in any specified length up to 3000 mm, in 1 mm increments. You get the exact length you want. Slim scales may be substituted for any and/or all axes for the same price. There are other options as well:

The seller, Wilson, has a good command of English and is helpful. The manual is in readable English. Three (four?) friends all ordered these (separately) at the same time, without any issues.
DROPros will sell you similar Chinese stuff for a lot more money, it will ship from Vacaville, California, and they will hold your hand and answer the phone in English and help you. Study, compare, and make your own decisions...
