Personally I like my Hawke Sport 3-9 X 40. It's under $80 which gives you some latitude for rings.
call Mike @ Flying Dragon and ask him about his REX 3X9X40 AO Scope. $55http://flyingdragonairrifles.org/REX_3x9x40_scope.htmli have 2 and will be ordering another soon. great scopes, forget how much they cost. very reliable, nothing fancy.not sure how much recoil your rifle has but Mike will know if that scope will handle it. bob
Re: scope for springer under $100mi just noticed that!!!!for a hundred million dollars you could get a pretty good scope!!!! sorry, couldn't resist. bob
