I would also go for a machinist brand, if Snap-On works the same way as european brand do, they just rebadge products and sell them for a lot of $$$.
I like mitutoyo, but there are other very good companies...

Being somewhat young, iv only used digital. Is digital better? Im also in the market for a mic.
As usual, it depends of which digital and which analog
...
If you compare 2 Mitutoyo (for example) micrometers, then in term of accuracy, yes digital will probably be better. Between 0 and 100 mm their digital serie is "accurate" (I don't know which K is used in the standard) at +- 1mic, their analog at +-2mics.
The good point for the digital is that the reading resolution, according that the reading measurement system is accurate (here part of the +-1 mic), is of 1 mic. Analog type have thimble graduated by 0,01 increment, if you want to go to the mic they use a vernier scale, it's easier to make a mistake reading it (even if you shouldn't) than with a numerical display, this add uncertainity to the measurement.
BUT, you should first know which accuracy (and idealy certainty) you need on your measurement (please don't say 0,001mm

), then take something of good quality that can handle it and maybe save money for some calibrations.
Analog have the advantage to never run out of batteries, even if good digitals are sobers, it sometime happens...
I'm equiped with all digitals, but it took me time and money (still do with calibrations) but if I had the money for only one good digital, I would buy a set of analog for the same price.
Big bad Jon is right in a way, buy some Starret or Mitutoyo analogs for mesurements and a HF digital to protect them from thieves
