Where can I buy foreign language recordings?

Your best bet is amazon.com. amazon.co.uk is also a good 来源 if 你 don't mind the shipping (assuming 你 are in the US) Occasionally ebay will carry one 或者 two as well.
Unfortunately a good deal of international recordings can run rather expensive for various reasons, and several are just plain Out Of Print.
Normally, I would simply offer to IM 你 链接 for various casts I have obtained from various sources and uploaded, but I can admire the desire to do things on the up-and-up. :)
