Cheers, last place I worked for had separate units, place before that I had a Fluke (I think 1653) which I got on with ok. I would prefer an all in one unit. I have had a go with a Megger which seemed good, hence if I'm having to buy one myself wanting to make sure I do it right first time. I'm sencing there's not a lot between Fluke or Megger other than brand loyalty. Thing is, if I get a Fluke will the 1653 do? Is it worth the extra near on £100 for the 1654? I'm thinking (actually praying I get work more like) that I will be using it for domestic, commercial/industrial, periodics in those also.
