Green Lantern for the subcategory.

I checked the site again and eReader does have a free creation software, called Dropbook, but it requires marking up the text with the Palm Markup Language. I have Studio, so I've never used Dropbook.

I've also downloaded Calibre and Stanza, so I'll try to make other formats as well. I think Stanza might be able to deal with PDB, but I haven't had a chance to play with it yet.
