definately buy the best optics that you can afford. There isn't much difference in the 200 to 300 dollar range the 500 to 700 dollar stuff is marginally better but the real leap is with the higher end stuff. If you glass continuously, day in day out. If the hunt is about more than meat in the freezer you will appreciate the better optics. We have all missed game that was there because we didn't see it. Better optics improve our chances of the really succesful hunt. The Japanese have steadily been increasing the quality of their stuff, and it is nice and light, there are so many binoculars to choose from because there are so many different applications to use them. As far as Antelope go the 10X42 are a good choice. Wind River is a nice product. I think you will be happy with them. A friend just bought a pair of Nikon. These are the telescoping model. I didn't like them, but he does and the reduced weight is a big plus if you have to move around alot.
