Tough question. I have taken scopes and binos out of a retailer to compare them for clarity, crispness, and low light performance .... but never a spotting scope. I would imagine very few would have a 2000-5000 yard view where one might make a fair comparison. I would depend upon reviews, and information others might offer here. The only spotting scopes I have used are a Burris that cost about $300, a Swarovski that probably cost $2500+, and a Leupold that probably cost $1000 +/-. The Leopold was plenty adequate for what we were doing - spotting out to about a mile. The Swarovski was absolutely amazing. The Burris we were using as a shooting range spotter. I have no clue how it would do in the field. I wold guess any spotting scope in the $1000-$1500 should do fine.
