I'm getting ready to take the plunge into rifle competition, specifically NRA long range prone, F-Class (F/TR) and Palma (when I can find a match) and I'm thinking I need to upgrade from my little 20x Nikon spotting scope that I use for backpacking.

What should I be looking at? I'd like to keep the price reasonable and I don't think I need a zoom eyepiece. Suggestions?
