I've been thinking about a new scope for the XS78. I'd like a bit more magnification than my 1.5x Weaver, so it's got to be a 4x. I'm considering the N/S Mountmaster 4x32, probably the AO IR incarnation. Is there something better out there? My budget is £50 tops - and it must be new, not s/h - fixed 4x and able to survive on a springer if required. Any ideas people?
