Good comments here. Absolutely go for quality rather than magnification. If it means you have to wait, then wait. Otherwise you'll just be waisting good money on a bad scope and your good scope will have to wait even longer (ask me how I know).
I regularly spot .30 caliber holes at 100 yards with an 8x Leupold rifle scope, and at 200 yards with decent 20x binocs on a stand. That's in good lighting conditions.
If 200 yards is your maximum, 60x is a lot more than you need. Less magnification will make for an easier-to-use scope, and a really good 20x will beat the pants off a poor 60x. My 4-14x SA rifle scope sees more detail than my cheap 20-60x spoting scope. The trouble is, I wouldn't have believed if I hadn't waisted the money and saw for myself.
Also, make sure the spotting scope has enough eye relief so you can use it while wearing shooting glasses. Seriously, I don't understand what some optics manufacturers were smoking, but the scopes you see on the counter at your average neighborhood gun store all seem to be made for bird watchers with contacts. For a shooter, (who, you know, wears safety glasses?) you have to take your shot, remove your glasses, spot your shot, put your glasses back on, then reposition your ear muffs 'cause they got shifted when you removed and reinstalled your glasses, repeat. Am I the only person who's has this problem?
