eric,
I recently bought a Nikon Buckmaster 6-18X40 for $315.00 out the door, and am well pleased with it. I have had zero problems dialing from 0-650 yds. So far it has maintained its zero while taking the abuse of my .300WinMag with stout 180-190gn loads. It can be had with the "regular" duplex reticle, comes with two sets of elevation/windage knobs, 4" sunshade and parallex adjustment on the side.
My .243 Win70 HVB has a Nikon Monarch 6.5-20X44 and my 7mmRM Rem700P has a Leupold VariX-III 4.5-14X40 and the BuckMaster is just as clear and as solid as these two are for a little less money.
MidwayUSA was running a sale on them for 299.99. May still be going on. JohnnyK.
