I would recommend a 10x42. if you read about optics they say a 4mm (divide obj x ocular 42 divide 10 = 4.2 )exit pupil is the biggest a human eye needs.These are handy for scanning wide areas for game. When you find something that catches your eye, then use your spotting scope to get a up close view.
Good otics are exspensive no doubt about it. I invested in a pair of Leica 10x42 Ultravids. Cost was a little more than a good rifle and scope, scope mounts, and sling combined. I justified the cost by three ways 1. I am young (28) and just starting big game hunting so if nothing drastic happens or I don't loose them (sic)[

[:@] they should last for lifetime. 2. They can be used on non-hunting trips out west to and around home. 3.I cut back on reloading and sold a couple guns and a spotting scope that were collecting dust.
IMHO decent binos start at around $250.00 I have used Minnolta's before and they were o.k. for the money you are talking about. Wind River is o.k. too. Have not used the Cabelas series yet, but have used one of there scopes it was adequate, not as good as a Leupold.
Money spent on good optics won't be wasted.
without a doubt the Leica 10x42 Ultravid is the most compact 10x42 available. Not the lightest, but the balance is awesome. The ergonomics, thumb rest could be positioned different but it is easy "to get to know these binos"
