I bought some digital mic's over time a while ago Mitotoyo and M&W mainly because I thought I should. The Mitotoyo were significantly discounted. M&W full price, I couldn't find the same size in Mito at the right price. I recently replaced the M&W one with another Mitotoyo and advertised it on here. As far as I can check them all are fine. The last one I bought did come from a dubious source – ebay USA look what I have type thing and several of them. They went quickly. The battery was flat. This is one reason why they sometimes come up well below list price – same with a crazy Draper one I mentioned a while ago that I think some bought –
I needed a mic of that size anyway.
My very 1st digital calliper came from an offers list that used to come through the post now and again. It lasted for many years and was very accurate but eventually the battery compartment started acting up even though they lasted a couple of years. Not being entirely happy with 6" I went for a mitutoyo 8". That was seriously discounted and just as accurate as the previous unbranded one. That one cost me £30, a lot when I bought it. At the time a very exotic item. It took months and months to arrive. Guess they obtained orders and then had them made. I'd guess accounting for inflation the Mitotoyo was cheaper.
Personally I think that it's best to have a sensible attitude about bargain prices. Part if too cheap and part exactly who is selling it.
Works for me anyway.
What do I use most though – my 0-1 and 1-2 from training days both with verniers and a 2-3 but at this size there's not much difference between using a cumbersome digital mic and an ordinary one. I don't use my Kanon vernier caliper as I know both of the digital ones are as good. I also have a rather tarnished 30" vernier one, Super cheap and i have even used it a couple of times.
