Completely reputable, royalty-paying publisher. Jupiter Gardens is the parent company, and Pink Petal is the romance imprint. PPB publishes all genres of romance, with the usual no-nos. Submission guidelines are on their site. Jupiter Gardens publishes primarily metaphysical and New Age nonfiction, and on the fiction side they do science fiction and fantasy/paranormal/urban fantasy.
The company is run by an author who took the time to learn the business of publishing, and she's grown it steadily and slowly. There are now editors working for her, and she regularly signs on new authors. They're very definitely in the business of selling books to readers, and the owner and her editors work closely with authors on quality control, promotion, etc.
I'm published under both imprints; I have a novella, novel, and two free reads with Pink Petal, and Jupiter Gardens is the home of my YA novels. My first release with them came out in September 2009. I receive monthly royalties, which have never been late, and the owner has been very open to negotiating contract terms. We've also worked together on finding new ways to promote my YA stuff, including building a website for my Reality Shift series. (Site isn't up yet; we're still working on it.)
Pink Petal is primarily an e-publisher, though there are two tiers for print for books over... I think it's 50,000. Authors have a choice of limited distribution print after a certain amount of sales which escapes me at the moment, or full distribution print (through Ingram) after 100 e-copies are sold. Jupiter Gardens books go to e-version and print pretty much simultaneously, with a gap of a week or two between the two versions but no minimum sales required for print.
The company has been in business for over two years now, and I would definitely recommend them.
