A lot of those screens are brand new, and there haven't been a lot of orders for them from this board. The screens are all TFT, and have very good LCD panels. Compared to screens by legacy, or other extremely cheap panels which are STN screens, they will be much better. The DS700HRS is a screen with a lot more features, where the 640 is simply a very inexpensive way to add a high quality screen to your car. You'll be happy with either one.
