funshooter,
It depends on what you are going to use your next purchase for, that should be the factor in what "highend" scope you wish to buy.
I have used both the straight 50 ($1,400) and the 10x50-52 ($1,800) March scopes on benchrest rifles...which is what they where designed for and by....check this website
www.benchrestcentral.com for some more info on that part of your post.
I also have a Tactical 36x55-52mm ($3,300 which includes a custom reticle with 5, 10 & 15 moa hold over lines with 1/8" dots) on an Open class F-Class rifle that is cambered in 6mmbrx, it is the cats a$$...beats the Nightforce in weight and power on both ends......priced fair concidering that they are almost one off type of production with only a few made each month. I kon't know of any better (equal) Target scope for the money on the Market today.......if Premier and Leupold had stayed together it might of been a different story. I still use some of the 20x50-50mm Long Range Target (new $968, now used about $1,100-$1,300 depending on reticle) scopes that Premier boosted in the late 90's.
If your really going to plunk down $1,500-$3,300 for a scope do your home work here on the web, check all the benchrest forums and also
www.6mmbr.com in both the forums and in the Daily Bulliten as they test and compare scopes and other goodies!
Not to be out done S&B and Sightron both have 50 power stuff out there now also....of course the S&B that I have cost more than the March and I had to pay Duty Import Tax when I brought it here from the World Championship last year.....a small price to pay for such great glass.
