I have several burris scopes. The turrets on the FFII are not target turrets, standard 1/4 clickable adj's. If you get a burris, I would definately tell you to get one that has an adjustable objective. Every burris scope I have, with the exception on one older signature 8x32, has had excessive parralax that is hard to fine tune. I have sent several back to be repaired.
I would also suggest going with more magnification, especially if you are going to varmint hunt with it. At least a 4.5x14 min.
In the value line of scopes, I would also suggest looking at Bushnell Elite 4200 series. Believe it or not, I think that they are better than the FFII's.
