You will spend more time looking through your bins than anything else so buy the best. Got to be Swarv's, Zeiss or Leica, and if you then want to upgrade you will get your money back, which you will not if you buy anything else.
I purchased a nearly new Howa .243, with Wildcat moddy and 7x50 meopta for £750 (from a dealer) and was hardly used so in that case it would leave £1,250 for your bins.
I think the concencus is that Swarvs are the best, with Zeiss/Leica a v close joint 2nd.
It is a lot of cash but you will not regret it. Also say you give up stalking there is a very ready and bouyant market for top end bins. Get yourself down to the Sportsman late in the day and look through them outside at dusk and but the ones which you feel most comfortable with.
