I ran across this call on Duotrope's Twitter feed for a new Argosy Magazine. They're looking to publish the zine as ebooks and will be paying royalties. Stories must be over 4500 words. They have three themed issues you can submit to. You'll find the calls here.
I have a bit of an uneasy feeling about this market. Their site first went up on June 16, the calls on July 26, and their guidelines on October 4. I did find a piece up at the Absolute Write site where the editor/publish has posted his call and answered some questions. There's nothing bad that I can find. But there is no editor name on the site and he goes by Dantai at Absolute Write so I have no idea who is actually in charge.
If they do make a go of it, this could be an excellent market for short fiction.
