I'm just starting to get into leather, and I really want to buy some gear.  Any recommendations?  I've shopped around Mr-S-Leather a bit, but they seem to be doing more and more rubber.

I'm not sure what exactly you are looking for.  If it is leather to wear, like chaps, pants, shirts, etc.  then try:
