Jimbob we can use my spotter if you'll bring me along on a sheep hunt.
Definitely binoculars. Unless you are assessing trophy quality you will used the binos 1000:1.
I will be moving out west in the future (BC) and plan on hunting everything (Sheep, goats, moose, elk, deer, maybe even grizzly). Right now I have cheap Nikon Monarchs 8x42 binos.
If you go with used there is a pair of vortex vipers in the classifieds that have been here for a couple weeks. Just have to checkout multiple classifieds for a deal, I just happened to look for spotting scopes on the local Craigslist a few weeks ago and scored a brand new looking vortex vipe HD 65mm spotter for 300.
IF you are looking at pre-owned binos you should look at a pair of Zeiss 10 x 40 Classics - Awesome binocular and I see them in the $600-$800 range on ebay all the time
