I just bought a used Mitutoyo 509-203 off of eBay for $100, and I'm kicking myself for not getting one sooner.
I previously had been using an iGaging digital height gage, which was about 1/2 the price of the used Mitutoyo when it was brand new, but I was never thrilled with it.
It worked fine enough as a height gage I suppose, and it's plenty accurate, but it didn't have a carbide scribe, and felt a little clunky when scribing centerlines. I finally bolted a carbide scribe to the hardened steel scribe that came with it, and it was better, but still not very comfortable to use.
The Mitutoyo is a night and day difference. Much cleaner scribe lines and much more comfortable to use.
Looking at the Shars, it looks very similar to my Mitutoyo, and they're a little cheaper. Looks like a pretty decent option as far as I can tell.
