I have more than a couple, I still use my shitty $3 one for continuity tests because it's faster and louder than my Agilent meter, but completely inaccurate for anything else. It's also super light weight and easier to retrieve and sling about.
I use an Agilent U1242A for proper testing, but its continuity test is crap, slow and quiet. I am looking to upgrade soon though, and resell the 1242 (I actually have two 1242's atm).
As far as testing caps, ESR is also very important, a cap can have good capacitance but bad esr, equivalent series resistance, and esr can kill a cap pretty fast. There are some cheap esr meters out there, but I have no experience with them. I use a Tonghui th2821b that's a dual read out capacitance and esr, it wasn't super cheap, but works great and I have no reason to believe its not accurate enough for what I do, but the manual was chinglish and otherwise useless, had to figure out the buttons on my own really.
I also have a spare new one for sale if anyone wants one for less than ebay prices.
If you want to know more than you need to about DMMs watch the eevblog shootouts.
Playlist for
meter reviews.
He really only reviewed a couple LCR meters in this
play list.
I was sure he talked about esr meters more, but this is the only
I found he did, pay attention at 5:30.
Of course there are tons of other vids and website with info about this stuff.
