There are some relatively decent multimeters on Amazon for about half the cost that offer similar or better performance.

I have one of these for casual use:

Multimeter, RICHMETERS RM409B True-RMS Digital Multimeter Button 9999 Counts With Analog Bar Graph Temperature Sensor Test AC/DC Voltage Ammeter Current Ohm - - Amazon.com

$42.99

Not my primary meter (Keithley 2002) but surprisingly OK... It's actually a pretty nice meter, comfortable to hold and in direct comparisons with the Keithley and Fluke, quite accurate. (Well really perhaps a bit better than the old Flukes tbh)

Another option with about the same performance as my 409B

RICHMETERS RM111 NCV True-RMS Digital Multimeter Auto Range 9999 counts Temperature Back light AC/DC Voltage Ammeter - - Amazon.com

$29.95

I edited post because I stuck the wrong link in the first time.

I do like that the RS Pro lists the accuracy for each measurement in their spec sheet
https://www.alliedelec.com/m/d/8ee25...7f4116e1b7.pdf

What I'd really like is a manual ranging one; a couple of times now I've glanced at mine and thought "how am I getting that much volts now?" and then noticed it was mV

The manual ranging ones I've found don't go very high on the capacitance for some reason.

I have a separate capacitance meter because I haven't had a good experience with multimeter based capacitance testers. I have an Agilent U1732B for measuring capacitors.

The Richmeters come with a pretty thick manual which includes a lot of specifications which for the most part I have ignored.

One of the things I find with inexpensive meters is that accidents that don't harm Fluke or BK Precision or Keithley meters generally kill them. I have few accidents but eventually forget to switch ranges and.... well you can guess the rest.. LOL

I'm not a fan of manual ranging meters, but if you must have one the old Fluke bench meters are nice - I'm thinking of 8050 and 8010 (have one of each), they come up used on eBay and elsewhere. The 8050 has nicad batteries (which I had to replace a few years ago, surprisingly they were original to the meter, but I left it on and unplugged a couple of times and they didn't really like that.)

I’m not familiar with RSPro but $70 seems a bit expensive for what looks to be a very basic meter. You should check out EEVblog and his YouTube reviews of various multimeters. The cheapest DMM EEVblog recommends is a $20 Aneng (I’ve never used one), he also sells his own branded DMMs which I have used and I like very much, you can find them on Amazon with free shipping. If you’re willing to spend more than the RSPro you could get a Fluke 17B+ (I have one and I like it), but the $135 EEVblog BM235 meter has better precision, more features and a very thorough manual: https://www.eevblog.com/product/bm235-multimeter. As for LCR meters I have an Agilent u1732b and. DER EE De-5000, I prefer the $100 De-5000.

"RSPro" is obviously RS/Allied's brand-logo on a standard generic meter.

I second the idea to look at EEVblog. I find the guy annoying, but he is usually right, peer-vetted by his huge community of meter-abusers.
