for $99 you can get a refurbished Nikon Prostaff 3-9x40. Haven't heard anything bad about them. I have one that I bought new and am very happy with it. I'll definitely be saving the 50+ bucks for the next couple rifles I scope by going refurbished.
My concern with Nikon is there seems to be an awful lot of refurbs out there....and they only carry 90 day warranties. I do admit to liking their scopes though.
