To the OP, you didn't really mention what you want them for (except to glass The Road for cannibals). Count me as another vote for more light collectivity, while I suggest a use you may not have considered.
I have a pair of Nikon Action 7x50. They were around $100, and they have some warranty that says, no matter what happens to them, I can give them back to Nikon with $20 and they will give me a new pair. These binos are not compact, but they collect so much light, I now use them at night to look at the stars when camping. I even use them for stargazing at home, even though I have two telescopes that are more powerful. Looking at the stars with both eyes, even just 7x, makes a huge difference, and it's much less complicated than setting up a scope. If your objective is less than 7x the magnification, you don't get as much light into your eye at night.
Several nights ago I was looking at the Andromeda galaxy. It's just a smudge, really, but it's the furthest point in space that human eyes can see. There are a bunch of star clusters out there that pop right out in good binos. If you can rest the binos on something solid (or a tripod), you can see the moons of Jupiter, which is visible right now after sundown.
So, if you like to camp out and might use binos at night, this is something else to think about. Do what Matt Danger said and get an objective that is at least 7 times the magnification. These Nikons are great, even during the day, but they are not compact.
