The $60 RPi screen is higher resolution, mounts with four screws (vs this one with three separate PCBs plus the LCD), and has an interface designed to be controlled by the RPi GPIO pins. I don't think saving $17 is worth losing all of that.
These are 7-inch capacitive touch screens, less than $70 from amazon prime, same resolution (800x480), mount with 4 screws, and use HDMI for video and USB for power/touchscreen. The downside is that the touchscreen drivers are binaries. Somebody online made an open source driver that appears to work perfectly, so if you're not using Raspbian or something else their binaries are made for, you might have some driver hacking to do.
