I too have used a Hawke pro stalk 4-14x50 since I started shooting 3 years ago. I got it for £75 from Optics with free mounts, delivery and BC flip-ups, which was half price at the time! It has never lost its zero ever and has now been on my FAC rapid for nearly 2 years and is spot on every session! Good light gathering ability in low light too! Worth the money in my opinion.
