I am automatically suspicious of subscription sites. They've made their money up front and have no vested interest in getting me a job. Not to mention the folks who own programmingfromhome.com aren't sharp enough to update their copyright notice on the bottom of each page (2005?
come on).
I've had good luck negotiating with my employers to get time from home (as we speak I'm sitting in my home office taking a break from work). Once I've proven that I can produce without constant supervision and am quick to respond when working remotely, my bosses have no problem with me working at home.
dice.com has an advanced search that will show only telecommute jobs and they're free.
