I'm no expert here, but would suggest this: Buy or Library check out Mule Deer's optics book, sit down and read it, and while reading it, use his info against a checklist you have made on what you want a scope to do for YOU.
With six to eight hundred in you pocket you should be able to to go with the BEST for YOUR USAGE.
Then when shopping, do the comparison thing with your list and actual scope specifications. You will find some that specify things like 3X9 that will actually be a 3.4x by 8.4, or perhaps 2.8x by 7.9, so on and so forth with the different specifications actually listed for scope.
Hope this helps some, anyway all that study may help slow down the "burn" in your pocket.
