Nix Comics Quarterly is well worth supporting, not only because the stories, mostly written by Ken, are great fun to read but because Ken pays the artists who illustrate his stories.
Issue 4 features cover art by Michael Neno as well as a story illustrated by Matt Wyatt. Michael Neno's work has appeared in the first three issues, and Matt Wyatt and Max Ink contributed to Issue 3.
If you haven't yet explored any of the Nix Comics Quarterly issues, for a mere $20 you can get all four issues and support a fantastic venue for independent comic creators. If you can contribute more, you can get ad space or even original art work from the issue.
