But whether they are the right tool for you depends on what you're trying to accomplish. The piezo-electric touch-probe scanner works well, although it isn't fast. It makes very clean scans, meshes them, and can export them as STL files. And it comes with a suite of software programs for scanning, basic CAD, and CAM. So for fairly small objects under 2.4" high, it's a viable 3D scanning device, if you're not in a big hurry. It's a nice solution for a jeweler, for instance, who wants to design a sculptural relief at a comfortable scale, and then reduce it, using the milling function to produce a smaller version.
As a mill, it's not as powerful as the Taig, although it's strong enough to handle light materials like wax, plastic and wood. The 1/8" toolholder is standard equipment in the US, and it's scaled appropriately for the motor; you can get a 1/4" spindle for it, but the motor's the same. If scanning is to be part of your workflow, then the MDX-15 is worth considering; you'd be hard-put to find as capable a scanner plus a mill for the price. But if all you want is a mill, then one of Roland's bigger machines, or a Taig, would probably be more appropriate.
