If FFP is not a big deal for you then I would look at getting a used 3-15 NF. You can pick them up for around $1100 and they're super great scopes.

The Viper PST is also a great scope new, but you're best bang for the buck is in something used. I really like the USO ST10 for around $900 used. They're super solid and repeatable with a very large field of view. They're fixed 10 power, but will get you out to 1000yds and negates the need for FFP or SFP.

Just my $0.02
