Which binos to buy

[Matthew.Blake]

My parents have been so kind as to book a villa for the whole family near the equator where the skies are clear and light pollution is low! Thusly, I want to get a decent pair of binos as I can't afford to fly my telescope there. I'm trying to decide between the Celestron 15x70s from FLO (£80) or the Revelation 15x70s from Telescope House (£50). Is it worth the extra £30 for the Celestron pair?

Make sure to try them before you buy them, my Revelation 15x70 produces images that are very hard to merge. Also check for astigmatism in either lens and whether they can remain in focus after ordinary handling.

It's going to be hard to try before I buy. Would distance selling criteria apply if I buy, then try and decide I don't like them?
