I actually do have a Pyramid 7.2" around here. One word - Terrible! Pyramid is the parent company to Legacy, and they both are exactly the same screen. They use STN technology, which is very low res, washed out color, poor viewing angles, ghosting, and fuzzy. If you want it for the backseat so kids can watch cartoons, go for it. If you want it for a carputer, find a TFT lcd!
Alot of people here will say anything non-vga is crap, but in all reality a composite monitor can do the job nicely as well. There are some people here that are quite happy with them. Using large fonts text is quite legible. But with an STN screen, there is absolutely no way to make anything legible.
Last but not least, use the

feature to read up on lcd's before you make a purchase you might regret.
