It's an antiquated bit of terminology, stemming from the fact that this book is over 30 years old.
Any digital multimeter you buy today will be high-impedance. Need a suggestion? An Extech MN35 is an excellent entry-level multimeter.
Eh, for the home use you're probably just as well off with any ole category II chinese meter for 20 bucks.

I have this one. Not sure if your radioshack one costs any more than that or not. But that's what I recommend for an entry level meter. Flukes are nicer (A lot nicer), but I've never found anything that wasn't a fluke any better than this one... And since I don't work with my meter professionally I can't justify buying myself a fluke.
I saw a review a while ago where they said the accuracy was reasonable for home use but the author would be leery using at 120v or above.
Good auto-rangers are so cheap these days, it's hard to justify even spending $5 on something like this. Look at this one for $22: https://www.amazon.com/Extech-MN35-Digital-Mini-MultiMeter/dp/B0012VWR20 You can get pretty nice ones in the $50 range.
You don't need a "multi hundred dollar" Fluke DMM to use a thermocouple.

I would argue that a bad reference is worse than no reference at all, since it can lead down an incorrect path. I just dealt with this with an E3D customer, he swore the thermistor was bad because his IR gun read 150C and the thermistor read 220C. I had him put a thermocouple on it.
The thermocouple read 220C.
The customer wasted hours troubleshooting, got frustrated - all because he didn't understand the limitations of his tools.
Use the right tool for the job, and understand each tool's limitations. Did you look into spot size/reflectivity/emissivity?
None of them will tell you the correct voltage. The only way to know the real Vcore your CPU is getting is to use a multimeter and measure the capacitors behind the CPU socket (these are measuring points for the Asus X370 Prime board). A reasonable quality multimeter can be bought for ~$20.
If you can't use a multimeter to measure what the voltage is then the voltage I would trust the most would be what you set it to (not read) in BIOS, LLC (load line calibration) will cause it to be a bit higher though.
This looks like the one I have.. dirt cheap. If your lab doesn't have a thermocouple, a lot of the entry level extech meter's come with a cheap one and builtin circuitry to read it.
I've had success with this toaster and those stencils on 0.5mm pitch QFNs, 0402 passives, and low pin count LGAs.. but be prepared to do rework. It helps to have a steady hand, high quality tweezers, and ideally a microscope.
Truth! You don't need a Fluke or anything fancy. A $20 meter is more than adequate. Though I kinda wonder what al you get with a $200 multimeter now.
Fair enough. Here's a less expensive alternative that I think is decent: LINK
Safety aside (given it's low voltage), I wouldn't want to go too crappy for the sake of reliability/accuracy.
For the ~$20 mark, I'd try an inexpensive Extech:

For the ~$50 mark, the EX-330 was well received on the EEVblog $50 multimeter shootout:

You can get a cheap multimeter that comes with a thermocouple that you can use to test temps.
