I use diamond disks (ebay) mainly to rough out the shape, then wet/dry 600 to 1200 grit sandpaper disks glued to a soft mandrel, and then a 1" buffing wheel loaded with diamond paste (the messy part, since the dremel runs way too high). I'm considering getting a bigger buffing wheel to use with my drill press, mounted sideways to emulate a polishing pad on a cabbing machine. Should do the trick better than my current setup. Since I do one every two months (when time permits and I don't have higher priority things to do) it has been okay but in the end the Dreme really is good to shape small cabs on a tight budget. For engraving it seems okay, unless you plan on doing really precise work, for which a dentists' tool (or a handpiece with a flex shaft) is the way to go. Might shoot a few pictures of what I currently use.
