I haven't updated my spread sheet for a while, but off the top of my head the scopes in a price bracket lower or similar to the Mark 4/5 with a better FOV are:
VX5/6, PST Gen 2, Strike Eagle, Razor Gen 2, Bushnell DMR/XRS & Match Pro, Burris XTR3, NF NXS & NX8, Athlon Ares BTR/ETR/Cronus, Delta Javelin & Stryker, All the other 4.5-30 LOW scopes (Tract, Maven etc).
The PST Gen2 and XTR3i stand out the most as offering excellent value for money glass wise and especially FOV.
If Burris put a decent cross over reticle in the 3.3-18x50 it's almost be the perfect crossover scope.
