If you are looking for a budget bino, I'd recommend the Leupold wind river series. I have a set of the cascades, 10X, that are actually pretty decent. I believe they make an 8X cascade as well. For the money, I really like em.
Ck out GR8fuldoug at cameralandny.com look for Minox 8 or 10X42 . I just got a pair of 15X58 and their really good. Their are quite a few good posts about Minox on this site. I sure like mine... Bill Maylor.
You would like the Leup's, very nice quality for a decent price and the best warrenty in the business. IMOP you can get a better pair of bino's for a cheaper price by going with the Nikon Monarch series. I have compared alot of them and I honestly think that for the same money (or cheaper) you can get a better bino with the Nikon. I carry plenty of the 8x42 or 10x42 and many other variations.
If your truely going to glass for mule deer regardless of the brand you will be better served by the 10 x. I used to have 8x steiners and they were just not enough to find bedded deer at longer ranges.
The Promaster Promaster - Camera Land NY Elite ELX ED would be better than a Vortex Viper, Pentax DCF SP or Minox ASPH but not quite as good as a Vortex Razor, Pentax DCF ED or Minox HG
