I'd have to agree with MM, especially for antelope to go with the spotter first. I bought binos first and do use them the most. That said, for judging animals I can't stand to be without my spotter. Even in the Midwest looking at whitetail I end up putting the spotter on the tripod or window almost every time I'm watching a buck I may be interested in. For example when scouting before muzzle loader season I spotted a great buck through my 10x42 Leica binos at about 1/2 mile. I knew he had a great frame and spread. When I put him in the Swaro spotter I also knew he had a broken G2 and about 2" broke off a brow tine. I could also tell he was likely a 4.5yr old buck by what I saw. It also helped age him that I identified him as one I had on camera last year based off a bulge that always looked like it may become a drop tine on his right main beam. Knowing what buck he was for sure let me use his habits from last year to help pattern him. I didn't shoot him, I took another buck and he has broken more points since then (hopefully next year I'll get to hunt him). When next season rolls around I will have two years worth of patterning to use. I learned a lot about keeping a journal for future seasons from Mike Eastman's books, it helps.
Anyway, when antelope hunting I really want the spotter to judge them before putting the time and effort into a stalk. Antelope are hard to judge anyway and a broken tip, mass measurements, it all makes a difference. I only get so many days with so many daylight hours to spend when heading out west to hunt, I want to make the most of them. I'd get the spotter and a good tripod now and try real hard to get the binos before the muley hunt down the road. You will never regret buying good glass. After having it I regret waiting so long.
Vortex is the best value in optics if they work for your eyes. I always wish the eyecups on the binos screwed out one more turn for my eyes. I went with Leica Geovid HD 10x42 binos and a Swaro 20-60x80 spotter. I have tried several Vortex binos and thought the optics were good, but the eye relief just wasn't right for me. The guy I hunt with bought a used Swaro spotter and sold his Razor too. I also have a Nikon ED50 spotter I really like, and my buddy hates it. Try to actually look through whatever you are considering before making a purchase and find what fits your eyes and budget. I'd buy your favorite with each purchase, not try to do it all at once. Save up and buy your favorite in the next type optic the next time you get enough set back. I'd have spent way less in the long run doing it that way instead of buying something and then selling it used to take the next step.
I have a couple tripods I like too, a Promaster 525T for carrying, and a Swarovski aluminum one for glassing where I don't have to pack it far. I have the Promaster 6160 heads on both. There are better out there but they work for me. I really like the looks of the Outdoorsman short-medium tripod with their heads if I was doing it over again today. I don't have any experience with them personally and would want to before buying for the cost. I have the Cabelas window mount for the spotter and like it.
These are just one man's opinion and there are more knowledgeable people on here than me. Bitterroot Bulls helped me a lot getting to where I am. Hope I can help you a bit the way he did me.
