First off Im not sure what display options youre looking for as in completely portable, bridal show booths, studio meetings with clients etc.
If it's a booth, and/or studio environment with AC power then the way to go is a flat screen tv...
Here's a Samsung 22" LED HDTV for $250 from Amazon:
Pixtus.com: Samsung UN22D5000 22-Inch 1080p 60Hz LED HDTV
I bought a Samsung 46" LED for my office that I use as a Digital Photo Frame so I know these work... They have a USB port where you can just plug up your thumbdrive with images and let it play.
At $250 I may just get one of these and find some place to put it!
