I really like vortex optics. Great value and an unbeatable warranty.
I did however just buy a primary arms 1-6x24 scope for my new build. I wanted to the the acss reticle and I've always heard pretty good things about them. The newer gen 3 model has a lifetime warranty as well. The older generations did not have that.
I paid $279 for it along with a mount. I went with a aero precision light weight mount.
