I’ve been very happy with the Nikon BDC line. Coupled with their Spot On app you can pretty much dial it in at any reasonable distance.
They’re reasonably priced and have a lifetime warranty.

I love my Monarch BDC. Goes on my Rock River in .308. I also have a Buckamaster on my .270. And a Leupold on my frontstuffer.
I recently updated one rig using a Nikon BDC. I like the way the Spot On app lets you e-mail field ballistics charts to yourself for later reference.
I like Nikon glass for the money.
Go with Nikon or Leupold...you can get em for under $200 here:
