I have the SB800, haven't used it on camera at all !! always use remotely !! Don't know if you will be able to get a SB800 anymore new as they have been discontinued, anyless someone has run out stock.
The other option is to buy a SB-26/28 and a wireless trigger and shoot in manual mode all the time :)
Good website/blog to follow, he is amazing... Strobist
