I thought he's budget is up to 1K  :-//

For those on that sort of budget, hold out about a week...

The "that sort of budget" is the confusing part. Is it the >$200 range, or close to $1k range?

No confusion there. If anyone has $1K to spend, hold off for about a week and an option may present itself...

I suggest go for a simple handheld multimeter something like a UT-71D.
With the rest of the money you build yourself a few 4 1/2 digit voltmeters with the good old ICL7135 / TLC7135. You just need someone that can help you calibrate the 1.000 Vref. With something like LTC6655B-2.5LS8 you are on a good way for stability in this case but there are a few other voltage references that fit the requirements too.
In most cases you don't need more than 4 1/2 digits, but it was settled into the head of some beginners to need >5 1/2 digit multimeter, for what ever, same story as with oscilloscopes.
Remember, 4 1/2 digit equals 15bit, 5 1/2 digit equals 18bit, 6 1/2 digit equals 21bit. Refer to AN82 (Linear Technology).
Metrology Meeting 2020 is canceled. Looking forward for MM2021

I've heard it's a nice unit, but I don't have one.

Be aware for the uV virus, it is an expensive desease  ;)

Yes I realize that it's not easy to have accuracy over time. I also understand that you can't have something good for $200. It'll age, but it should still be better than my 0.5% mastech. I'm reading reviews and information about high accuracy multimeters/standards and I'll eventually gonna buy one. I don't (yet) need uV accuracy. My idea is to have 10 times more accuracy than I need soat the end I could have 0.1-0.2%.

Aging of voltage references is something I would love to play with. I guess it has to work all the time?

Btw, I'm waiting for those up to $1000 multimeters reviews.
