I'm not sure, but there was probably an explanation in some forum thread. Many people from this forum bought Brymen multimeters from TME, once it was one of the few stores where you could buy them in the EU (offices are in Poland, Czech Republic, Slovakia, Hungary, Romania, Germany, Spain, Italy, Netherlands - you can call and ask about the differences in the WB version)

I recall reading somewhere that WB stands for White Backlight - in contrast with the horrid original green backlight and the slightly newer orange backlight also present in other variants.

The display backlight has been changed in versions marked with the letter "S"

Based on the budget constraints, I would go ahead with a higher count and/or more accurate DMM, but without at least a calibration (cal + data is better IMHO) it would not be recommended to adjust any other equipment based on it.

You could have three DMMs that all agree and disagree with your power supply, but all you "know" is that the three DMMs agree, you don't "know" that they are right.  But for some folks, that is enough for them to adjust the power supply due to the odds, so it's your call.

I still don't really think the calibration is neccessary for my use case: DIY perfboard electronics, arduino projects and the occasional fixup around the house. Not really like I need it for fixing 100 000$ equipment for a company. I just want to be reasonably sure that I'm not accidentally giving my circuits like 6V instead of 5V. So if it's like 0.0005V out, that's completely ok. I know that it's not properly done, but then again, I can send the meter for calibration afterwards when I have the money/need for it.

The whole point of me getting a more serious meter is that I don't want to rely on a cheap piece of crap (no offense to Aneng) and I think a higher end multimeter will be more stable and trustworthy even without the calibration. Plus the added safety and features mean that I'll finally have something I don't have to be nervous measuring the mains with.
J-R:
It makes no sense to lump Korea, Japan, China, etc. together, as they are drastically different situations.  Probably best to edit your post.
