Let me share you my thoughts of my last DMM purchase. It might help you (or others).
I ordered a Siglent SDM3045X for <300 Euro in China including UPS shipping which is a quite useful instrument for this price. It has decent quality and has 60.000 counts with 4.5 digits. Thus in the range of e.g. 3V or 5V it has the same resolution as 5.5 digit DMMs with e.g. 120.000 or 240.000 counts. Both will show e.g.
3.3000V - the 5.5 digit version will
not show a digit more if the value is >1.2V or >2.4V. This is why I liked the 60.000 counts 4.5 digit Siglent. It will show the same amount of digits up to 6V.
Other reasons I chose this: My budget was 300 Euro and I knew I can sell it anytime - same functionality as the 5.5 and 6.5 digit (SDM3055X and SDM3065X) units (and maybe the 4.5 digit version can be hacked to 5.5 digits - but for me there is no need to do this). And I wanted a visible logging functionality without the need to use any PC software or to add my scope. And Ethernet and USB / copy data/screenshots to USB were on my checklist.
I had a Rigol DM3058 before and I did not like the small and crowded display. I am getting older and like large numbers

Practically I didn't need/used the 5.5 digits of the Rigol - 4.5 digits are fine for me until the count is >50.000
What I excluded right from the beginning were these used VFL display units (Agilent, Keithley) as you never can trust the photos, and I did not want to end with a dimmed version, where I have to invest a lot of money and (more important) time to change the display unit. And I also did not want a unit with LCD display (like the older HP units) as the LCDs are slow and often difficult to read.
Of course I know, the precision of this Siglent unit will probably not match up after 10 or 20 years with a Agilent unit, but then I probably do not want the unit anymore anyway (I tend to exchange my gears after a few years). I am very pragmatic and to be honest: I do not need to measure 1 picovolt differences on a 3V systems, so I do not need 6.5 digit units.
