I agree with the Fluke. Buy a good basic one, take care of it and it Will last a lifetime. I would not want to risk an expensive rig to an inexpensive meter. Only takes one bad reading to ruin your day.
I pick up the Harbor Freight free meters and keep several in "stock" to give away to people who don't have any meter and would like one. They seem to work OK for casual use.
I am a long time Fluke meter user though, and it is my meter of choice for the rather extensive electrical diagnostics and work I do on solar systems. In fact I have three Flukes, one in each car, and one in the house. But they are not necessary for most people. Sears, Home Depot, Lowe's, HF, and even Walmart have decent inexpensive digital meters for occasional use.
I had a cheap one from Harbor Freight. The leads literally melted when testing a 24v battery (2 12 v in series). I believe I had the unit set for 12 v. So I got one of these from HD. It was on sale, but here is is from Amazon http://www.amazon.com/Klein-Tools-MM.../dp/B00EO2HFPI There is a slight delay when connecting the leads (since it auto ranges). It seems very well made and good for novices.
When I was working, I had a fluke T5 1000 that was sufficient for most of my needs. But you won't need a voltage requirement like that one at 1000V in a non-industrial application. You would want a clamp meter to be able to assess current draw through the current carrying conductor. Very useful to assess your amp-hour requirements for RV battery and inverters/converters. Make up a 3 wire extension cord of about 1 foot length with #14 stranded wires and a 120V 15A connector at one end and plug at either end. This is a very useful device whenever you need to determine current draw on any 120V appliance in home or RV. Just clamp meter around either current carrying conductor to check amperage.
The only problem with the clamp meter I used was that it did not have a high resolution to read fractions of an ohm accurately, but I don't think this would matter in most cases anyway. Check the specs on the one you may want to purchase. You can get a good, cheap analog multimeter at Home Depot, Lowes etc for $20 or less I think. These are nice to have for battery voltage checks, low resistance readings, continuity etc.
Another very useful tool is a voltage detector. Gives an audible and visual signal when voltage is present but does not indicate voltage measurement. You can determine if there is voltage present in any unshielded conductor without needing to access termination points.

I found that I miss the 'continuity' function on my newest multi-meter. If you have a choice try to get that because it is the fastest way to check for a grounded hot wire or a break. Also if you can, get a set of alligator clips with the meter plug in ends. Trying to hold the pointy things and read the meter while standing on you head .....you'll see that one day, I guarantee!
You get what you pay for. I was given one of the harbor units from my Dad it was never accurate trying to monitor battery charging was very frustrating. I now have a Klein very happy with it. I have a friend in the Xray repair business and he checked it against his high dollar instruments and found it to be very accurate within its limits. I paid about $120.00 at home depot. Rand
