HotDealFinder - it's hard to say how good (quality-wise) those binoculars are, but I'd venture to say your money would be better spent at Kmart or WalMart. It's most likely they're the same binoculars, with one simply being a "camo" color versus the standard black/gray. The lower price simply reflects that the "camo" binoculars are less appealling to the average person.
The "standard" size for binoculars is 7x35. As j00 correctly points out, the first value represents the magnification "power" (ie. magnifies the image "x" times), and the latter the size (diameter in mm) of the objective glass. While higher power serves to make the image you're viewing larger, it also has several major draw-backs. One, magnifying the image *also* magnifies any "shake" in your hands (often referred to as 'camera shake') - so if you have a very steady hand this is not (as much) of a factor. Two, magnifying the image reduces the clarity of the image as the binoculars are essentially spreading the image over a larger area of the retina. This can only be countered by using larger objective glass to "collect" more light, which in turn adds to the weight of the binoculars. And when you're out hiking over several hours, having even 50 ounces (~2 pounds) hanging around your neck becomes extremely uncomfortable for some.
I would avoid other "improvements" such as variable zoom binoculars. Why would you look at an object at 3x magnification when you can view it at 9x magnification? Variable zoom is just a "marketing gimick" - they add nothing of value to the binoculars and only serve to reduce the overall quality of the image and increase the weight of the binoculars in general. It also increases the likelihood of repair as there are more internal moving parts.
My recommendation - if you're simply looking for the cheapest deal you can get, by the Cyberrebate binoculars (in the absence of knowing who the binoculars are manufactured by). Otherwise, go to Kmart or WalMart and compare what they have by looking at distant objects in the store. You'll also have the added protection of being able to return or exchange the binoculars if they prove to not be very good in low light, or too heavy in the field.
