The Leapers scopes have worked pretty well for me, as have the Millett. I had a Millett on my varmint gun and it never let me down. I have heard less than complimentary things about Millett from other shooters, but haven't had any bad experiences myself.
Probably the BEST value in scopes right now is Nikon. They have some excellent scopes at very good prices. You can get a variety of scopes in the Buckmaster line for between $200-$300, and they are awesome!!!
What are you wanting to use the scope for? Knowing an application would help. If you let me know I can give you more info. Lance
