Just like with any lcd monitor, the more you spend the higher the resolution. I picked up a fairly cheap 7 inch one from Radio Shack for my dads bday this year, and it was around 60 bucks I believe. Not super high resolution, but it was nice enough! I wouldnt mind having one myself. But remember as with all new tech gadgets, they go down in price over the years. Go to the stores yourself, they have them setup. Look for features like the types of memory cards it can use, AC adaptor/battery power, etc. A lot of places like CC and Best Buy have reviews you can also read online.
