I've been on both sides of this decision, and I think a lot of it depends on the industry, and seniority level of the job you're applying for, as well as your industry.
If this is for some hourly, relatively junior gig, I think it's totally okay to quit as soon as you find a better job. As an employee, your ability to project leverage is far diminished compared to your employer in these scenarios, so I don't see anything unethical about utilizing it in this case, so long as you are honest and forthright in your communication with both parties.
I think the higher up you go, the harder this decision becomes. Think very carefully if your industry is insular, or your move could ever come back to haunt you, even in several years...since people remember this sort of thing.
