I just received a very nice rejection letter from Shimmerzine. I know it's odd to say a rejection was very nice, but it was.
Their senior editor took the time to write an email geared toward the specifics in my submission. She was very polite. Before submitting, I had also sent them a question which they answered in about a day's time. The usual turn around on submissions for Shimmerzine is about three weeks according to their site. I got mine back in about three days. Overall, I was very pleased with their professionalism and personal approach.
They are a great paying market of $10 per. They do mainly fantasy with some science fiction and horror. I'd strongly suggest giving them a try. Even if you're rejected, they're very gracious about it.
