Digital Photo Viewers?

Does Any body here use one that is portable and can connect to the camera? I was shooting some pictures for this family last Sunday, and thought it would be nice to be able to show them samples of what they were going to get. And any advice on a good one, and one that isnt REAL super expensive too. Any responses will be greatly appreciated!
Thanks,
Grady

I have to ask if you are showing old work, or what you just shot on site? Because the answer is easy, if you are shooting on site, a laptop with card reader is the way to go. Just scroll through the images in windows media if you have to. But if you are showing old work, a laptop is still the best, connected to a widescreen monitor. Nothing fancy. You don't need it. If I am showing my old or current shoots, I just bring my 17 inch laptop and let it go.

Portable TV hooked to the camera's video out port? Maybe a portable DVD player with video-in or a memory card slot there are a few I've seen from time to time)?

At some of the other events I shot a year ago, I had a digital frame, only takes CF or SD cards and nothing else, no RAM inside it, and put in only the images I wanted to show and let the frame scroll through all the images. If you have one of those lying around, they are pretty cheap now.
