There are a lot of inexpensive DMMs around. I have several of the $5 Harbor Freight meters and they have worked perfectly for their intended purposes. One I left on my boat to check the alternator output and state of charge. Three were used for my grandson't science fair project describing Ohm's Law. I have a couple still in their wrapping. They are great for making gross measurements that don't need to be very accurate. One day I'll check the accuracy with my DMMCheck standards.
The thing is, these aren't 'electronics' meters as Dave would define them. One thing he wants is a uA scale and this eliminates all of the 'electrical' meters. They simply don't have that scale.
One of the less expensive meters that is suitable for electronics is the Brymen BM235 and, if you buy this one, you might as well buy the EEVblog variant. Very cool meter. I bought two of them and gave one to my grandson.
The EEVblog meter is $125 at Amazon:
https://www.amazon.com/EEVblog-BM235-Brymen-Multimeter/dp/B01JZ1ADCOOver in the Test Equipment subforum there is a spreadsheet describing a LOT of meters. Oddly, it doesn't include the the BM235... Most of the meters are very pricey. High end, no doubt, but probably not what one would think of for a beginner's meter. There are a few meters that are sub-$100.
I realize that $125 is a heck of a lot more than $30 so it may be out of the question for many beginners but maybe it will be a possibility somewhere down the line. Just try to make sure the candidate meter has a uA scale. It will be important when designing amplifiers and such.
Download the manual and print out the accuracy specifications. Then, as you evaluate other meters, compare against a known baseline.
I just bought a GW Instek GDM8251A bench meter for $125 off eBay and it should be here in a few days. In general, I don't think much of buying used test equipment, particularly meters, because I don't know how badly they have been abused. Students? You can bet that these meters have been hammered! Still, I can hope it all works out. More to follow if it doesn't...
