The definition of “a lot “ varies widely with people so I am going to address the ‘good’ part of this question with a couple of options. To me, for a spotting scope to qualify as good, it needs to be in the 80mm exit pupil class and should have the “high end” glass. Some companies call it HD glass, others ED. If a company puts their high end lenses into their optics, it usually means they have included better prisms and coatings as well. The scope should waterproof and fogproof. I feel like we have found a scope that fits the bill. The Viper HD from Vortex sells for $300 to $700 less than other highend scopes and performs very well. Come in and give it a look.
