I remember spotting some decent quality tokens on here or story-games.com which were similar to the ones used in the book, but I can't seem to locate the PDF now. Anyone know where these are?
They're in the Agon Resources sticky thread here:

Miniatures are a great alternative to tokens, if you have the time and interest. Using the minis, along with a battle board, has added a lot to the Agon games for our group.
The Foundry probably has the best Greeks, but there are lots of options out there. Also, Reaper and many of the other mainstream producers have virtually every monster in one form or another, plus the D&D pre-painted lines offer a lot of the classic Greek creatures.
