With a budget of $2k, you have options.
Rule #1: When buying glass, (and most other things) you get what you pay for.
Rule #2: see rule #1.
Also, as mentioned in previous posts, a spotter (even the best of them) is limited by the conditions that you are using it in. The image quality at 10,000 ft on a 30 degree clear sunny day will be much different than the image quality at 100 ft in July on a humid day in the south.
I had a Vortex Razor HD 65mm spotter for a couple seasons and it served me fairly well. In good conditions, it performed surprisingly well. In poor conditions, the image quality suffered significantly. On a hunt, I had the opportunity to compare my spotter side by side with my buddies Swaro sts HD 65 mm spotter. In less than ideal lighting, the performance of the Swaro was MUCH better. I sold my Razor and bought a Swaro sts HD 65 mm and have never felt like I needed more scope. This spotter is amazing.
I went with the 65mm because I pack my spotter on my back, so I didn't want the extra weight and bulk of an 80mm spotter. I also read good things about certain Kowa spotters, but I have never looked through one.
Good Luck
