18months ago I was in the fortunate position to be able to buy a pair of RF bins, I went down to the sportsman and came away with a pair of Zeiss 10x45's and a pair of Leica Geovids 10x42's HD's. I trialled both for a week and optically they were the same as far as I could tell. Rangefinding was also very comparable. The ballistic programme on the Zeiss is really a bit of a gimic, however the range finder is a single button push, cf 2 on the Leica. I liked the Zeiss red round ranging circle. However after a week I returned the Zeiss and kept the Leica's as the were just that bit more ergonomic. I have not regretted my decision, they are a truly outstanding bit of kit.
The deal you are able to get from USA is very good and you could get more for them if you decided you did not like them.
I was going to write a big review article on the above, but time is a premium. I have lots of photos of both. If you want any more info, PM me your no and I will be in touch.
