I used Leupolds for years with great satisfaction, but a couple of years ago I wandered around the SHOT show specifically looking for a new spotting scope.
I tried every scope in the house and decided on this one Optolyth MINI B/GA 15-45x80 Spotting Scope
I think the Optolyth spotting scopes are the best available today.
The price is now a bit higher than you stipulated, but this scope flat out delivers. And if you check around you may find someone with a great deal.
That said, the new Gold Ring Leupolds are outstanding and will serve you well for at least your lifetime.
And a quick zip through OpticsPlanet.com just now shows some outstanding deals on MeoPta, Swarovski, Leupold and others.
