I dont like have the shot of a lifetime and a 50$ scope. The cheaper scopes arent as clear. If you want a good deal on a scope look into a refurb of a good brand name. Natchez Shooting supplies sells alot of refurbed Nikon and Burris which are both top names.
I sight in guns for peeps who dont have time/patience to do it themselves and its pretty obvious the difference in cheap stuff. I dont think you need a 1000$ Kahles scope but why buy a 500$ rifle and put junk on it.
