Although this post isn't probably relevant anymore i've just purchased a Sieg KX3 and I am really happy with it for a small mill. I purchased it second hand off ebay but it was like new. All I will say there was about 0.07mm backlash in each of the screws consecutively and the chap who had it previously hadn't compensated for that in Mach 3 and he was complaining about the finish on his parts.Click image for larger version.  Name: 21151470_10154834488745233_8125463378769032547_n.jpg  Views: 1580  Size: 80.1 KB  ID: 22764 This was only part of the problem the machine is heavy for a small machine but if you see on the photo the guy had it on the shittiest stand imaginable which was a self build and was causing the majority of his machining issues as literally it would move everytime the machine made a cut. I am currently in the process of building a high quality enclosure and changing the standard R8 to a TTS/ Tormach Tooling System holder with Pneumatic drawbar. I will do a seperate post on that and please check out my Youtube vids.
