Unfortunately in the optics world you do truly get what you pay for. Swarovski is the best. Hands down and has been for years. I have looked through every glass out there and continue to as they come out. Zeiss and Leica are great. Also expensive. Some of the higher end Vortex are good. Those are the popular brands. Try some out first. I would advise going to a big outdoors store but try to get the salesperson to go outside with you. You just can’t get a good feel inside the store.
Also, depending on what size you are looking for and the type of hunting, factor in a good sturdy tripod. It makes all the difference.
