Amazing Stories, a magazine with a history spanning back until 1926, is being resurrected - go to http://www.amazingstoriesmag.com/ to see for yourself.
Most of the content of the "Relaunch Prelaunch" issues is available online for a limited time, so it's worth going back once in a while, and checking what is coming on-stream.
Or you could, of course, just pay the $1.99 for the full editions - actually, I'd recommend you either do this, or donate something to the effort!
