Try the Bishop texture by frank. Photorealistic and FREE. Really nice for the price. On the cheap, the Brad texture from spectre3 is very good and versitle. spectre3's textures are all pretty good, and he doesn't charge that much for them either. Working your way up the price ladded, the BreathGen Iago and Leo textures from Zetastudios are excellent (from SteffyZ who did Edo), and Catherina's Leonardo with the free heads available at her site are great too (met4d). Her site say's they're releasing the new Angelo texture this week too. I've seen the previews in the galleries, and it looks to be one of the best.
