Decent cell tones?

Hey, sorry for the semi-n00b question, but I'm coming up blank scouring google.

I'm looking for a website that has decent J-Rock, JPop, or Anime related ringtones. There are plenty of monophonic and even some polyphonic ones out there, what I'm looking for are the new-style MP3 ringers. I've got a Sanyo PM-8200 on the Sprint network if that's an issue. I've also got full Vision services, so I can browse to any normal website, if necessary.

Any suggestions?

Make your own. Edit down MP3s or MIDIs to ringtone-length snippets (cut down the bitrate of MP3s to mono/22050Hz/32kbps). Upload to web space, type the URL into your phone's browser, and there you go.
