I used to be a member of the IEE before it changed its name. OK on theory but I'm no electrician, sorry! 
I was an electrician originally then an electrical contractor for the rest of my time till I retired 9 years ago, what's the problem?
Fluke and Megger were always the 1st choice but they were expensive, because I had a few guys working for me I tended to buy them reasonably priced ones from the wholesalers, each electrician had upto 5 different instruments before the all in one instruments came out. Because our some of our installations were tested every year and we had to show the inspector calibration certificates for all of our instruments I made up a resistance board starting at very low ohms ie 0.01ohm up to 1megohms
and used to get my personal instruments professionally calibrated and then used these to check all the other instruments.
Any instruments that were out by 5% I then used to have these individually calibrated.
In a 10 year period I only had a couple of these instruments that needed professionally calibrated and that was usually the case after some damage to the instrument.
At the end of the day more expensive didn't relate to better instruments, so basically answering your question in my opinion it's not worth paying the premium for the named brands as long as you buy the instruments from reliable sources ie electrical wholesalers or RS

Thank you for your time and detailed explanation. It confirms what others said about the top brands. I was after a Fluke, but at £1600 won't do much than other competitors. I have a little experience with megger, and Kewtech, and a resolution of 0.001 ohm is not to be sniffed at. I kind of set my first choice on Kewtech 65DL, 12 IN 1, does all that's needed for 18th edition AM2-3, earth resistance for TT, 10mA to 500 and 1000mA rcd auto ranging, and even PAT testing. It can do EV with an adapter.
My future use will involve some remote locations, TT rod testing Ze and 3 wire spike method. Not all multi-function testers can do the 3 spike or even coil test. Kewteck does. It's black Friday, but, I think I will research a little more and buy later on.
Thanks again.

We had a few Kewtech, as good as anything else we used. We used a separate earth tester as most machines didn't include that facility a few years ago.
One of the places where I bought a few testers from were the calibration businesses I used, one of them was based in Maidstone called Alpha Electronics, used to pick up mainly the next day and their prices were competitive.
