Megger and Fluke seem to be the market leaders (in MFT's anyway). Personally I've got a Megger MFT1502 , I've tried a Fluke but couldn't get on with it.
Whatever meter you decide on give Megger Mark a PM, I think he does deals for forum members.
There have been plenty of threads on this i think there even was a poll, Personally I use a Fluke 1652 which has had a few problems over the years but they are good meters. If you do have any problems Megger Mark is a good first port of call he repaired mine last time and don't even remember being charged. Just put business his way and he will look after you.
Speak to one of our forum sponsors M M, he will do a good deal for forum members, he will also spend time to find out which MFT you need, rather than want.
Take a look at the Kewtech KT 65, as for Flukes (have got 1653)there ok but poor on dead tests (no constant testing) and Meggers (have got MFT 1502 plus single units)are expensive for repairs.
