In reply to Guismart:
It's always a trade off in some respect - I needed a pair that were small enough to carrry around and would go in a rucksack or jacket pocket, were reasonably robust, had decent optics but weren't so expensive that I'd wince buying them or weep endlessly if I dropped them. I ended up with a pair of Nikon Aculon A30 10x25. About £70 i think. Perfect for what I need, but you pays your money, and you takes your choice.
For reference, a pair of 10x25 Leica will set you back about £350 and 8x25 Swarovski about £500. The price of good ones goes up exponentially the bigger the objective lens, so you're better off settling for better smaller lenses than bigger poor ones
