I have a 20-60x80 Bushnell ELITE that I intended to use for target shooting. Fantastic glass! I only ended up using it in the summer once for a birding trip...and now it's listed in the EE if anyone is interested.
Bushnell has been pretty good at making very high end products at middle of the road prices. Their spotting scopes are no exception. I recommend always going with their ELITE line if only for the warranty, not to mention the performance.
I had a chance to look through some others before I bought this one. The swarovski 80mm was a beauty! A bit long in the tooth though. The compact spotters were pretty good, but the 45mm objective models were a bit dull at distance with high magnification. The bargain spotters were fuzzy at high magnification and also fairly dull....hard on the eyes but they did the job.
