Most journals in the fields dominating the arXiv (physics, math, CS, and probably more) allow you to submit to the arXiv concurrently. So unless you refuse out of principle, you can both get free refereeing and release the paper open access.
I'm aware that most subdisciplines of physics and CS are sympathetic to arXiv, but that is most certainly not the case in bio and chemistry, although the rise of biorxiv may start changing things.
