I can vouch for the Varmint scopes too, very good bit of kit for the money. The AGS 3-9x40 or 50 mildot scopes are ok too and quite a good price.

Depends how much you want to spend really. If you're that new then I'd agree with what the other chaps say, go to a club first and talk to a few people. You'll get good advice and more than likely you'll get to have a go with club/members guns.
