I use a pair of
Bushnell Excursion 8x42 binoculars that I bought a couple of years ago.
They were my first 'good' pair of binoculars and I have to say I've been really pleased with them. I think I paid about £120 and rather bizarrely they came with a free tent - presumably so you could go on an excursion with them!
They're a decent size and feel nice and chunky in your hand but not too heavy (for me anyway, my girlfriend struggles if she has to hold them up for too long). They're pretty rugged with a rubberised outer so they should (and have) survive(d) a few bashes and they're fully waterproof and nitrogen purged so they won't fog up. They have fully multicoated, bak-4, pc3 optics as well apparently which I presume is a good thing though I've no idea what it means!
They've got a really good clear field of view and though there can be a teeny bit of colour fringing at times its not really noticeable. one of the coolest things about them is actually their close focussing, they'll focus on stuff only 2 metres away which is great when you manage to sneak up on something!
As I said my girlfriend wasn't so keen on the weight so she got herself a pair of
Nikon 10x25 Travelite EX last year for about £110. They're pretty tough wee things as well, rubberised, waterproof, nitrogen purged and multicoated optics again. Much, much lighter and more handy to carry about in your pocket.
They're 10x rather than 8x and you do notice the difference, they're also exceptionally clear with no colour fringing at all that I've noticed.
Against that the much smaller field of view (25 rather than 42) means it can be harder to get things in your sights. I was watching Golden Eagles last year while she was still trying to find them!

She got there eventually
They're also not quite as good in low light conditions as they obviously collect much less light through their lenses than the bigger pair.
A bit under your budget I know, I don't know what extra stuff you'd get for another £80? It could be that another £80 would make a big difference

A good idea might be to find a local shop and go in and try them. You can always buy online cheaper once you know what pair you want!
