With the larger machine I would go with the integrated display and oil/water proof sensors. I am not sure what type of sensors the inexpensive iGaging scales use but they can be cut to length which I had to do for my mill. The advantages of the integrated displays puts them in a much higher level than just the scales with individual readouts. I have not had any contamination problems with the inexpensive iGaging scales other than one bad cable. I did make some "scale covers" from light weight cloth just to keep the chips out but they are not oil or water proof. The integrated readout panel sure is interesting.
For the larger lathe I would certainly want oil and water proof scales. The shielded cables look very nice on the 2 axis that C-Bag noted and I would want that for the lathe. I did not put them on the lathe since the lathe is so small I thought they would be in the way and would certainly get oil and coolant on them. On the mini mill they are a bit more protected and the inexpensive ones seem to work pretty well.
Hope I answered all the questions and thanks for all the comments.
Good Find C-Bag, hadn't seen these B4. The specs/functions look pretty good and actually think the scales look well built and enclosed with flex metal cable jackets. Ya just never know about repeatability which to me is an important spec that generally only the upper end ones give. It may be caused by the scale interface to glass or the readout...diagnostics would be tough. Also keep in mind the scales are 5.5" (141mm) longer than your travel for mounting them so scout where/how to mount them. The other thing is the reliability of the interface...it's probably a long wait for replacement or service and the only guarantee is "Your satisfaction is guaranteed", what ever that means, but Ebay does and will assist and for how long...whose noseż
All in all for ~$200 to the door is a great price for 2 axis glass scales and lots of toys on the display. Think it comes down to finding a lot of what others are saying about these, seller and ask about the guarantee in writing before purchase and if they have calibration specs and a manual. 2 - 5* on Amazon, different seller. 1 -2* on the 3axis.
Quite a broad range of categories in his store also...from blowup bouncers to jewelry ring stretchers...Guess you pays your money and takes your chances.

Elsewhere I saw on eBay this same DRO and there were 3 actual reviews. They were all amazed it seemed but had no clue how long it would last. But as usual there was one clinker who couldn't figure out how to mount it. So I have to add "windage" to these kinds of reviews and one liners that just say "won't recommend" but won't say why. But when you see there has been a bunch sold and no bad press, more windage.
There seems to have been a quantitive drop in prices of new unbranded and branded DRO. I have a tendency to think all these things are made in the same place, just with different names on them, but also possibly to different spec. You just can't get that kind of specs out of them because either they don't have the expertise or language barrier. Add to that you can't get guarantees on anything electronic now it seems. More leap of faith, don't get in a hurry I guess
Sorry again JR for the hyjack, but it's nice to get some eyes on this inexpensive DRO question along with some opinions.
