Best binoculars a I ever had were Zeiss Dialyt 10x40. But if you increasingly wear glasses then no. The eyepieces are roll down not push down...a big disadvantage.
So I now use Leica 7x42 BA or a pair of Optolyth 7x50. I bought my son the Leica 7x42 HD. Never really been that much struck on Swaro stuff. If I want something with greater magnification I use my Grey's telescope.
But keep permanently a cheap little Russian Tourist-4 'scope in the car. It does for checking flocking pigeons or anything else of interest. So the cheap Cold War Soviet, Czech Meopta or East German Jena stuff still has a role even today...if you put it down and forget it you don't cry!
In Suffolk, although I think they are somewhat pricey, take a trip to Cley. To Cley Spy. On the Norfolk north coast. Client base appears mainly for "twitchers" who, by reputation, are more obsessed with their "glass" than are stalkers.

They have hundreds of binoculars, new and used, Zeiss, Leica, Minox, Opticron, Swaro etc., etc., etc., and a three hundred yard field out back to look across to some woodlands. All prices from fifty quid up to a thousand quid and beyond. You may find that what suits what you want to do is somewhere between those two sums.
