As far as cheap goes, I have always found that a good ebay supplier is cheaper than any private website. Pm me and I'll give you the names of one or two I have purchased from in the past and my experience with them.
I can't stress enough you should probably play it a little safe and spend the extra $5-10 and get the full laser WITH DECK/MECH (KEM-400) and not just the laser alone (KES-400), especially if your single laser system is playing one type of media and not another. You could get lucky and actually have a good laser and just a bad mech.
Have you done all of the major safe mode stuff?
