I am an electronics technician. My employer buys me stuff that costs more than my house. There is Fluke and there is everything else.
If you cannot afford a Fluke, that's ok because it's probably far more meter than you'll ever need anyway. Many hobbyists will want to start a pi$$ing match about ohms/volt accuracy, number of digits, autorange response time, multi-frequency, blah blah blah, but unless you are a professional who has a defined need for these specifications and the training to use them, don't worry about it. The average prepper simply needs to check basic voltages, continuity, etc.
The three things I look for are a study case, the type of battery, and the test leads. The guts are pretty much all the same so look for something that won't vaporize into pieces if you drop it once. Batteries are an issue too. Some meters (especially old Bell System units) use whackjob batteries, or several button cell batteries that cost more than buying a new meter. Also, even good test leads will eventually break; test leads are not intended to be a lifetime investment. You should buy several extra sets. Don't forget fuses too.
Analog meters: They are essential for aligning tube radios and are basically EMP proof. They need batteries only to measure resistance but are not as accurate and lack a lot of the functionality of digital jobs.
If you can have only one meter, get a digital model. But multimeters are like flashlights: Nobody can get by with just one and they don't necessarily have to be top quality. I personally own perhaps six or eight meters, both analog and digital. I keep one in my truck, one in my toolbox, my test bench...you get it. None of them cost more than $100 new. Most are older Radio Shack rigs and they work A+.
Multimeters are great to have on hand as barter/charity items. You can get a surprisingly good meter for as little as $5.00 and I've even seen them on sale at Harbor Freight for $1.00. Post-SHTF they will be excellent currency.
If you are still set on a high-end unit, good used Flukes can be found for less than $100. There's a lot of Agilent and HP stuff on the used market too.
One of these days I'm going to make a post about the value of oscilloscopes, frequency counters, and signal generators!
