My wife moaned when she heard about this and tried very, very hard not to kill me. I was pretty much over the hardware acquistion project, whereby I buy lots and lots of computers, gadgets and video equipment to fulfill my dream of becoming a living media center - a self-sufficient photography, video, and publishing studio.
Anyway, read up on the Nikon SB400, a smallish easy going speedlight that isn't your full fledged speedlight, but certainly one that meets most of my needs. Because I'm home so much, and so much of my shots of the kids are indoors, and also because I live in a state whereby sunlight is in short demand, a speedlight like that would be so great.
It costs about a hundred, which isn't small change, but it certainly isn't too out of reach. I should be coming into some wedding money soon - maybe if I do my gigolo dance and shake my ass a little, my wife will consider it. It's funny though, reading on all the photography forums, a lot of the photographers always have the wife factor. One of them had the same dilemna, and after some forum help, the guy said, "My wife curseth thee!"
The rollover photos on this review shows what difference using a speedlight can do: I certainly didn't know.
