Tbone,
I have the leupold 15-45x60 that you looked at, and I really like mine. My buddy Doug sold a swaro for the leupold and hasnt regretted it at all, mainly a weight issue not a quality issue.
I think that particular scope is about the best going for weight, optics, size, and durability, you'd be hard pressed to find a better scope.
As to the price...I'd bite the bullet and get what you'll be the most happy with. If you buy the right scope, you'll never need to buy another. I've given up on trying to save a couple hundred on important gear...in particular binos and spotting scopes. Good glass is worth every single penny. I glass better and more with optics that dont strain my eyes.
If I had to make a choice between an inexpensive rifle and quality glass or inexpensive glass and a quality rifle...there isnt even a choice. You'll use your glass way more than you'll ever use your rifle...
