Any Binocular experts?

Im after some good-ish binoculars. I was heading toward the £70 mark.

i want them mainly for looking at wildlife/ birds.

Have been mooching a lot, and found a couple that look quite good.
Firstly, the compact -

and also this mid sized Nikon.

I do like the chunk of the Nikon, but if the Pentax has similar specs, then it would be silly to carry round extra weight.

anyone got one of these? any tips?

thanks!
