Hey Jim!

A quick look shows it to be a mfg generic site. No sales tray, suggested prices, nor distributors listed. Digging around, the few Unimeasure items I could find via Google were hundreds of dollars apiece, which as stated is not what we wish to pay. From the spec sheets, their LX-PA-25 looks -about- right, but searching and Google Shopping returns NO sales hits for it whatsoever.

Where can you buy them (esp at surplus prices, if possible)? <edit> What did you get, and what did you pay for yours? </edit>

Do you know: Does Unimeasure (or another maker) make a unit that fits the spec of this discussion, or are we back to trying to make something that approximates it, to reduce cost? ( 25" cable, 0.1" resolution [IOW repeatable to about that error band], don't care about linearity, ~$20-25 each ballpark...)
