Totally Stainless is a great company to deal with on stainless fasteners that are automotive style and their prices are good. They also sell ARP fasteners at the best prices I've found anywhere.
As far as stainless steel bolts made in Asia, virtually all are these days except ARP. There are many stainless steel fasteners that are as tough as grade 8 bolts. They even make stainless U bolts for rearends. The main thing is to understand the grade of bolt you need for a particular application.
