Actually I'd like to find an Aurora Igniter or other card. But if I'm going to go that route I'll probably hold off for a high-end version. I have a Igniter breakout box (and other currently for sale on ebay), just no card at the moment.

There are some Asante GigaNix cards on there. If you go to the Asante website there's one page with a long list of cards and info on them. I looked through that to find the ones that work in OS 9. I believe one even had OS 8.x listed. There was one (1000TA I think) on ebay for something like $2.99 but shipping from Canada was ridiculous.
