Carson makes some decent glass in the $200-400 range. That brand is very popular with the bird watchers and has a fantastic warranty. I’m on my second pair, as the first pair broke where the harness connects. Sent them in and they sent me a new pair all inside of 7 days.

I also have a set of midrange Sigs in 10x42. They are maybe a tad better than the Carson but a little lighter.

Swarovski is on my list and I will eventually end up with a pair. They are worth the cost if glass a good bit.
