In this case, I think you can go with whatever looks good to you. I think all of these options are made in SE Asia. The S-9, S-9X, and S-10 on the drumfactory site (which are all basically P-85s, but with different looks) are probably made in Tawain or China, the Gibraltar stuff I know is made in Taiwan, and (someone please correct me if I'm wrong) I think the Ludwig is an imported part as well. So, being that they are all the same mechanical design and all imported, it would stand to reason that they will all perform similarly.
Oh, and the snare butt doesn't come with the strainers at drumfactorydirect, but a new replacement butt can be had for the high price of.. $1.85! (Coughsnarewiresfor$4.27Cough)
Mikey, how is it that you have NOS 60s Pearl replacement strainers? I didn't know they were ever available?
