I did notice that there is a $25 rebate available on the SB800, it expires March 31.
Here is a Nikon page that has some detailed information about the two flashes. Including the Instruction Manual for each:
I am retired but during most of my adult life I made my living as a newspaper photographer. I've been converted to digital photography (not an easy transistion). I'm trying to get back into photography by taking wedding photographs on a limited basis. My question: which flash should I buy and why - the SB600 or SB800 for my Coolpix 8800. As is true of many retired people I have a limited income.
