There are so many good thoughts on these forums! I've enjoyed participating for many years now and after a account reset I'm back to the beginning. So I'll introduce myself and start over.
My names Scott and I'm a 50 yo southwestern Idaho hunter that has "guided" my 3 sons to multiple freezer filling adventures. I hunt archery elk, and all other critters with rifles. (and occasional blowgun) Our primary means of hunting is backpacking on long, steep, hot (or freezing) enormous mountains that make my legs and lungs explode. But every year we return for the same experience. Fortunately we fill the freezer most years so we enjoy the heavy in, extremely heavy out experience. I currently own factory rifles, medium quality glass and try my best to create custom reloads for each gun. I'm happily married and have a daughter that wants a "sniper rifle" so she can shoot a deer next year.
Here's where my perspective on the question by the OP. Most of our glass is medium quality, with one rangefinding Leica bino. We run two spotters (Zen Ray and Vortex) on every almost every hunt.
Glassing off of a tripod is hands down the best way to find game. Anyone can see game walking around in the open and in daylight, and can do so with cheap glass. Finding slowly feeding or bedded game is another story. I wish I would have started this practice sooner. We glass with 12x and 10x bino's. Anything over 12x I can't handhold very well, its too shaky.
If I don't bring a spotter I regret it. We are always spotting things we want to check out without moving a mile closer. It just sucks to carry 56 extra ounces all over the place but the spotter is something we never leave without. I too cover an eye with a hand if using the spotter for hours.
So for what its worth I'd recommend spending the most money you can on quality glass and a lightweight tripod. If I could only take one it would be 12x binos, but thats because we hunt areas where we only seem to find game on ridges 2+ miles away! Haha
I can only recommend having both.
