I often start with Fleeting Fancies, when I'm hitting a new fandom. Becky kind of has everything but TezuRyo in there, though she does have a fanart section for them, but hers is probably the most extensive PoT archive I know of. It's mostly the older stuff, since she's since moved her focus to other fandoms, but she links a lot of good fic.
And, um *tries to overcome embarrassment over tooting her own horn* I have a fairly large archive of fic, including some TezuRyo, if you find you like it.
