Shop for a used pair of swarvos after the new year if you want to upgrade. I see slc sell for 900-1000 often.
I wouldn't buy a 500 spotter. Again, shop used and save some money on alpha or even lessor.
As far as getting by with cheap glass, sure it works. You're kidding yourself if you think the expensive stuff is just for counting points. You're not counting poinys at long range. The value is finding animals. I pick out animals bedded, often. An ear or a back, bits and pieces for them standing etc. I've been through cheap glass and won't waste time on it again. They are not the same. I can see more with good binos than I can with a cheap spotter.
If I had to choose between binos and spotters on a hunt with a lot of glassing, I'd take a spotter. But I don't so I take both every time. To the guy that says people never use one, I'm guessing we hunt differently. I never leave home without mine and I don't whipmer about the weight. It's without a doubt one of the most valuable pieces of gear I have.
