Hi Nick and a very warm welcome back.
Assuming that you're referring to all-round "sporting" springers, choosing from any of the following will see you good, dependant on size, feel, handling etc. Be sure to try as many as you can to determine which will suit you best:-
Weihrauch HW77, 97, 98, 95, 80 and 35.
Walther LGV and LGU.
Air Arms TX200 and Prosport.
Diana 280 and 34.
If you are to include used ones, the choice will be even more vast and I'd be including Birmingham made Webley Longbow, Tomahawk and Stingray. Maybe even a BSA Superstar. And then if we're looking at modern classics, the choice gets wider still....
Any that you're fancying in particular and what sort of shooting do you intend doing?
