I found the exact 4-battery replacement (with snap attachment on top!) at an online electronics.retailer, but had to purchase a lot of three. I don't need the other two, so I'll sell them for just $6 each to the first two folks to contact me mark@irregardless.net.

That default combination is in your user's manual. I'm currently searching frantically for mine! Gee, how could I have misplaced it.
