Slug Guts,
the scope cost me around $500 with the case. As far as useable power goes with a spotting scope, there are very few times that you can use over 30x effectively, usually only in the early mornings, once the sun gets up mirage is a real problem and detail is very hard to see, in the cooler higher elevation area's you might be able to extend the use of over 30x for a bit longer, the most useable power range is between the lowest power up to around 30x, in the late arvo, it will be a lot less. It may be a different matter with the high end scopes such as those made by Swarovski and Leica. Yep, I got my Buck this year.
