Had to Google (other searches engines are available) that 'cos I'd never heard of them. There was one on Ebay for 250 quid - a screaming bargain if it does what you need. Even comes in a Fluke-style case, not the the annoying one that my (personally preferred) Megger is condemned to. Aside from the "big two" I think if I didn't have the Megger I'd be tempted by the Kewtec KT65. These all have the same issue for the first time purchaser. It is a lot of beer vouchers and you really want to work with one for a few jobs before parting with a grand-or-more for a new one. Final point, can't comment on the Fluke but the Bluetooth facility on my Megger 1730 is a complete fail. Doesn't connect or work is any way that a £1,000 device should and my 20 quid headphones do.
I'm whinging - I'll bugger off!
