I'll second the idea of thinking about "good used American" equipment.
I'd also suggest you at least think about getting a Starrett 0-1" micrometer, used or new. You will use it a *LOT*, so why not get a good one.
Thre are other good U.S. brands, too. A friend of mine swears by Lufkin micrometers. They aren't even made any more, but they are top-quality. If you can find a "good used" one, it ought to serve you well.
As far as the Chinese stuff goes: some of it is surprisingly good...when new. But in my (limited) experience, it tends to wear out fairly quickly. And some of it is surprisingly bad, even when new.
Personally, I think you'll do better to buy GOOD equipment, used or new, even if it takes you a while to save up the money. You will never regret buying a Starrett micrometer, or anything else. You'll also never wear it out, unless you are hopelessly abusive to your tools, in which case buy the Chinese crap because you'll never know the difference anyway.
Regarding your list of equipment: I have a set of micrometers 0-4", but I bought them over a period of 20 or more years. I got the 2-3" and the 3-4" used, when the opportunity presented itself. I hardly ever use them.
You will use a 4" micrometer about once every three years, if my experience is any indication. For now, buy a GOOD 0-1" micrometer (did I say you'll use it a lot?) and a GOOD 0-6" dial caliper. That will take care of your measuring needs for now. Then, as opportunities (or a well-defined need) come along, get the larger micrometers.
I wouldn't bother with the depth micrometers, unless you have an extremely clear and well-defined reason for getting them. After 22 years, I have yet to think I need one. A depth gage, maybe, but even that is somewhat superfluous.
Why do you think you need a micrometer stand?
Telescoping gages? Yes. And get GOOD ones. Starrett. Their use depends heavily on "feel," and with Starrett you can feel what you're doing. The imports are more clunky and aren't as good. I know Starrett telescoping gages cost a lot. They also work beautifully and you'll never be sorry you bought them.
Dial indicator? Yes. With a magnetic base. Be careful of buying a used dial indicator. I've bought a couple that have seemed fine on first inspection but have been well and truly worn out, as I discovered when I actually tried to use them. If you buy used, see if you can get an option to return it in 10 days if it turns out not to be satisfactory.
Once again, Starrett, Interapid, etc. are GOOD. The Chinese ones are probably good initially but will likely wear out quickly. Buy a good one, once, and be done with it.
You'll also want to get a set of small hole ball gages. Like the telescoping gages, they are extremely dependent on "feel," and it's worth getting good ones.
