cjk commercial use embedded

cjk for commercial use


I am having trouble finding the right (meaning cheap) cjk font for a client and I was wondering if anyone already had the same problem (and solved it). ;-)
The fonts I am looking for will be used digitally on embedded devices, as webfont and for apps and software.
So the question is, are there any free cjk fonts for commercial use avaliable? Probably not, but just in case...
After researching the web, it seems that all the smaller foundies are getting the same cjk fonts from one of the big global foundries. Does it make sense to ask a whole bunge of foundries around the globe? Should I ask an asian foundry? Are there any price ranges? And if so, what's the best way to getting a cheap font?
