Instead of Fraser IS I would suggest the new Kite APC 16x42:

You can order them directly from Kite:

I ordered a pair 2 days ago and the service by Kite Optics was impeccable: they sent them with DHL Express and I received them in 24h. Besides some glare issues I cannot fault them for much else:
-the IS works very well: totally silent (no clicking or any other noise), no delay, and rock solid.
-no button to press: the APC system detects the angle--->vertical&up=off, else=on (there is a switch for the power when the bino is stored in its case). Also battery life=120h!
-good/standard eyecups with three click stops
-they're light (about 750g) and easy to hold
-CA is well controlled on axis, and is average off axis (it's OK given the high power).
