Sorry...things have been hectic...Now you didn't specify Tactical or Hunting...but being the .260...I am going with Hunting and Target...
For that price range...and variable..the list is long...I forgot to ask Max Distance..but I will go with it anyway...
Companies...
Leupold
Bushnell
Burris
Nikon...and a few others.
One Really Nice scope that is not heard of but I got to play with one awhile back is the Shepherd Scopes...They are amazing...for hunting and also used by the military on M-14s...
So where to start...being I am not all that up on Leupold...A great scope but I think abit over rated and priced...even though I have a Mark Two...
I am thinking for you a Bushnell Elite 4200 or 6500 or maybe a Nikon Monarch or Monarch Gold...would suit your needs...all can be had for under the 1K mark...
Example...
Nikon Monarch 8x32x50 with side focus for about $700...
Bushnell Elite...4200 price range 5 to $600 depending on model and options.
and the Tactical..7 to 1K...
The 6500 Elite...750 to 950 depending again on options ...
I am looking at powers x16 and greater...
The Burris line is not bad either..
ranging for 400 to 700 in the Full Field style to the XTR..XtremeTactical..which runs 650 to just over 1K...
and lets not forget the New Kid on the block...Vortex...
They also have some impressive scopes....ranging from a few hundred to just over 1K+ as well...so you see, there are many options out there...
My best advice is to check a couple of sources...
Midway USA is one...I have there master catalog..
As well as Optic Planet..
I know this may not be of much help..but for now..it is the best I can do untill you can give me EXACT options you are looking for...
Go to Midway USA and go to the optics section...Have alot of time to look..you can pick your options and it will give you the scopes available in those parameters and price...

Hope this helps..
