Substitutions for BC557 and BC547? - Can't find BC55x transistors

Are there any substitutions for the BC557 and BC547 transistors available here in the US? Neither Jameco or Digi-key have anything like these numbers. And they're the best sources I have access to.

Thanks!

Any fairly high gain small signal NPN and PNP transistors will do. Try something like 2N3705 for the BC547 and 2N3905 for the BC557.
