I'm not clear on whether you mean some specific
chips or in general, but here is my experience.
For things that are in current production or recently discontinued, I have had extremely
good luck with Chinese suppliers either from Amazon or Ebay. For things that are long out
of production, such as 1802 (normal, not SOS) and 6502 processors, I've heard way too
many horror stories so I look to ebay for new old stock or used from US or sometimes
European suppliers. Again, I've had very good luck. In fact, I can't remember
every getting any bad ones. YMMV

Standard TTL 74XXX is drying up rather quickly. Futurlec still has some
TTL but 7404s are all gone. Even LS is hard to find.
