I purchased one of this same brand from someone on ebay for even less & was able to pick scale lengths. I took a chance (1) because they were cheap, (2) could get a 36" & a 24" scale rather than the standard mill or lathe package (3) was to be installed on a VTL that arrived here about the same time that the pilgrims landed at Plymouth. I was afraid the machine had to much wear on the gibs, & might destroy the scales.
It has been going for well over a year now without an issue.
The hardware package that came with mine was really pretty good. Very nice swing arm for the readout itself (wee bit short for my taste). the cables are very flexable & well shielded with flexable metal jacket conduit. good ssecure attatchments for cables.
As with most cheaper items there was just enough in the mounting instructions to guide you through safe reader to scale tolerances but not much else. Operating manual not completely useless but close.
Came with a 2 year manufacturers warranty for all that's worth. It shipped from Hong Kong. There is supposed to be repair depots here in the US somewhere, but I didn't research it.
EDIT: I should have read the entire thread before posting. I see that you are done. Oh well maybe someone can make use of the info for a similar project.
Very nice looking install. I have made 3 very custom installations on machines that were manufactured before DROs were invented. Hard to do but all work very well.
