Greek papyri font?

[sacklunch]

Hey all. I'm looking for a free/cheap (unicode) Greek font that mirrors the sort of typeset you find in papyrological journals. The most obvious difference for this font is the sigma (c rather than σ/ς). I have found a couple older/'beta' fonts (not unicode) floating around ancient personal websites (who knew geocities was still around?), but found no indication that such a font exists/is the standard for papyrologists.

This is what I use for Greek text crit:  http://www.ifao.egnet.net/publications/publier/outils-ed/polices/#grec

TLG also has a pretty full list of fonts if the above doesn't work for what you need: http://www.tlg.uci.edu/help/UnicodeTest.php
