Hi
I am about to purchase a new 8X42 birding binocular but I dont want to break the bank. 
I was going to spend up to £350 so any advice would be wecome.
Cheers
Try before you buy - as many as you can up to your max purchase price. Go for the ones that you like best over all - Simples!
Also check out the second hand bins on offer - I've just listed a pair!!!!!!! (not 8x42 tho')

If you can get to the Bird Fair at Rutland water next weekend there will be plenty of pairs to try.
