I was at a job last week shooting hotel rooms and meeting areas for a client, and when I tried to fire up the flash it was dead. I checked the batteries, Energizer Platinum(new), and one battery was corroded. A quick cleaning of the contacts and some new batteries didn't fix anything. Here's my question...I hadn't used the flash in a couple of weeks, but That wouldn't cause the corrsion, would it? I'll just have to send it back to Nikon for repair, as I'm pretty sure they won't give me a new one

Also how do you all think the SB-900 compares to the 800? Personally, I like the convenience of the off-on switch, but the 800 has a little more power.
