I guess I must be the odd man out. I am not a fan of tripod adapters at all, for various reasons. Tried them for a year and haven't gone back. Finding a spot to set up and glass, digging out a tripod everytime I want to glass, the awkward position you have to be in to use them on a tripod, etc. Totally not worth it for some minor if any gain. I can stabilize them quite well while sitting or with a trekker pole. I don't have any issue finding game and highly doubt I would find any more/less with a tripod. When two guys are glassing together there isn't much to miss, and you usually both find the same animals. I think why people are so enamored with the tripod method is their eyes aren't trained up to find game, so you can focus better on a more stable image? Either way, its not for me. YMMV.
The only glass I would recommend is the big 3. Look for used, if you can't swing the new stuff. Its a lifetime/long term investment... I've looked through some of the top end brands like Vortex, etc, and they are very nice as well. I also look at it down the road, which one will hold its value. Start with high quality binos and then get a spotter. You can find used Swaro/Zeiss/Leica binos for $8-900 if you are patient, and spotters for $1300ish. Don't buy a spotter with objective less than 60-65mm
That 50mm Razor is garbage. My FIL has one. You're much better off with a quality pair of binos. One overcast day, I spotted 3 caribou bulls on rocky ridge about 3 miles off. I couldn't tell how big they were, but could see them plain as day. When we pulled out his Razor, you couldn't even make out if they were caribou or a rock at 33x. Putting my Zeiss on them, it was easy to see one was for sure a shooter, and the others were small/medium bulls.
Where good glass is separated from the junk is in bad light/twilight, and also with eye fatigue. I can sit and glass for hours and not get eye strain. With cheaper bino's I get a headache.
