The VX 3 units are a step (albeit small) above the VXIII units. The 7's are being discontinued to be replaced by the new (soon to be out) VX6's. Leupy's are ok IMO, they do have a wide array of reticle options and a good warranty. The trouble is you pay for it. There are tons of great choices out there that rival and better Leupold at many price points. I only have one Leupy left as I've upgraded most everything to much better optics.
