I only have one, a 6", bought on sale. It's silky smooth & brings a smile to my face. That came after a rash of crappy ones that had one irritating thing or another at 20-40$ each so the bar was set low. Sadly they wont die. Over time the low level stuff seems to be getting better. Less battery eating, less 'must zero display' with each use. You don't feel bad if you drop it. Tools are a personal choice. If you move up the ladder to Asimetor or certain Fowlers & other house brands, the price multiple is more like 50-75% depending on the model. Clough-42 has a good video talking about this aspect & he made some good points about how they all are subject to a bit of human / tactile / part specific error. I came to the same conclusion just measuring & re-measuring a 123 block without looking at the display, just by feel. Shocking as it may seem, the exact same number does not come up 100% of the time. Micrometers are better in this regard, they have smaller contact, usually a thimble clutch. But I don't own any big ones.
I also want an 8 or 12 precision measuring stick for the occasional job but I cant justify Mitutoyo over other things it I need more. For me it's a low use item for the lengths I predominantly work in. I keep looking for a nice old school dial Mitutoyo caliper in that length, but the clean ones hold their value. And buying that proverbial 'lightly used by a retired toolmaker' that looked like it was salvaged from teh Titanic is not without its risks unless you are into resto's. So maybe that's the way to fleece your brain. Its an INVESTMENT. Yaaaah, thats the ticket. I'm doin it for my Kids! LOL
