Do you guys have GAS or you buy only the gear you really need for your job?

Do you never get any tool just because it's cool?

Of course. Cool tools are similar to purchasing a motorcycle or a musclecar or any other "boy toy", things keep us mentally healthy and alive, maintain testosterone levels, etc.

How many of you have a DMMCheck Plus or equivalent?
I have some cheap reference LCR and Voltage from china a couple of vishay 0,005% resistors and the lm399ah 10v reference from circuitvalley

That's on topic :)
I have three well-aged Trancell/Cropico zener-based references, a Fluke 515A, and some vintage saturated Weston Cells, plus a 7 decade KVD.
I have some Guildline and similar 4-terminal reference resistors, and some reference capacitors.
All were bought relatively cheaply - patience is a virtue :)
Mr. Scram:
To be fair, a DMM with a large screen and the ability to plot and do other things can be a real time saver. Seeing a trend can be invaluable. I remember the first time I used one I was thinking that this was going to change a lot. You can work without but especially in a professional setting convenience and time saved is money earned.

That's why i recommended the 34970A/34972A (basically a 34401A with a multiplexer): You can get a used one for half the price of the 6500, if you connect it to a PC and use its data logger program you basically get the "novel" features of the 6500 for half the price (minus the touchscreen of course)... Plus, having more than one channel for measurements can be really nice (i use mine to measure a few voltages+current simultaneously).
The only minor problem i have with my unit is the fact that it can only measure currents up to 1A directly, but luckily current shunts are a thing.

With a scan card the K2000 and DMM6500 can multiplex too. The DMM6500 can more easily do more complicated setups because it can be programmed on a computer or the device itself. Most other DMMs can more or less replicate a similar setup but convenience and expediency are a factor. I've rolled my own code but it's usually a more significant investment than I'd like so just poking at a screen for a few minutes and getting similar results is an advantage. The massive dynamic range is nice too.
