OH, there is a new SB400, but I suspect this flash is under powered, lacks many controls of the above flashes and would only work for your indoor shots. (IMPO)
After I bought my SB600, I added some accessories which were actually included in the SB800 kit: 1) Color Gel pack (~$30), 2) PC connection (~$20), 3) diffusion dome (~$20). So I probably should have bought the SB800. I believe the SB800 also has a built in optical slave (SU-4 mode) which is another $20 accessory.
I hadn't really planned on using it off camera at all, but after reading lessons on the strobist site. I use it more off camera in manual mode than on camera.

And the anti-twist plates...

Please note that their cheaper Quick-flip models don't have a anti-twist plates. But this is another option. Also be aware that the best place for your flash is about 12" directly above the lens... and you'll need an SC-28 or SC-29 for your iTTL flash. Yep... it all adds up. But you'll be happier with all the proper equipment.

I was gonna get the SB600 but decided on the SB400. For me the main factor was that with a smaller flash I'm much more likely to acutally carry it and use it.
I just didn't see myself walking around with the large SB600 on my camera but will probably leave the 400 on it most of the time. It's also alot more powerful than the older Nikon flash I'm using now.

So, if you don't need the additional power/light (can afford it) not big deal. But if you need it and don't have it... well... This decision is all up to the individual shooters preference.

I have the SB400. I look at convienance. While the 800 is way more powerful, it is way bigger. I like walkaround photgraphy and I like small size. I would not use the 800 as much and my needs are filling in light for shadows and some inside photography for getting moments. I put on a light diffuser, point it up and bounce the light. Get nice fill in light for the face as well as light bouncing off. If I am shooting in low light, I take the diffusor off and point it straight ahead. I needed something more powerful that the built in that also allowed bounce lighting. The 400 fit the bill.
I would use the 400 80% of the time and the 800 20% of the time. If I had just the 800, I would still use it that much because I hate bulk. I know the 800 would do 100% of the work, but it would be left home or out of the bag anyway. The 400 is small on the camera and small in the bag. Works for me.
Quote from Op: "I usually shoot outside or inside pictures of children."
As he said... all he needs it for are outdoor and indoor shots of his kids; therefore, the SB800 would be overkill, for a job that a $115 flash could do. But you're completely entitled to your own opinion on that.

It's dusk, the kids are at the back fence and "the event" arrives and you want to catch "the moment". Is the SB-400 going to have enough reach @ 20-30'? OK never mind... Dpreview answered that question for me.
But I guess I've always been one to think ahead. One can always grow into an item. But if you have to sell one to get what you really need (and the same applies to lenses), seems like a waste of time and money. This thought process is what I try to maintain when buying things I know I will use.
