i have had both. both have been bad for me.

the tasco i had on a win 9422 in 22 mag. after 5 years it broke and when i would put the magnification up the reticle would do circles. the B.S.A broke on my 35whelen and would get foggy at the lowest variable.ion that note i have several friends who have had luck with there tasco' s. but foggs up like you wouldn' t believe !!
if you don' t have the money for rigth now look into e-bay.. you might find some decent scopes cheap ! but between the two i would go with the B.S.A.
