Anything that is HW or Beeman R series. HW30, 50, 80,95, HW97K, or Beeman R1, R7, R9. You will have to decide what caliber, power level, or application you want to shoot. Since this is a BR column, then an R9 or HW97K might be good choices in .177 cal. If you just want to plink or hunt, then any of them. The only other springers worth considering IMO are the Air Arms TX200 or the new Walther LGV or LGU series. However, the Walthers haven't yet developed the reputation that the HWs or AAs have. Check out what rifles FT or BR shooters are using. That's a pretty good indication of what's the best.
