I own four PST scopes, Gen 1 and Gen 2, and one Razor. As others pointed out, this not a low end scope. The PST is #2 in the 5 tier Vortex line, just below the Razor. IMO, the used PST Gen 1 scopes are one of the best values out there right now: FFP, lighted reticle, and a lifetime warranty. If you doubt the tracking, do a box test and send it back to Vortex should it fail. Don't second guess your choice: you did well!
