We used both. Briefly, the 7000 has a USB connection rather than serial port, and is quicker and more reliable for editing on a computer, which is essential if you want to take advantage of the features. The 7000 displays many more colors than the 6000, and has a very natural appearance, whereas with the 6000 you must convert to palletted color. The 7000 has programmable hard buttons so that your cursor functions for navigating through DVD menus can be done on hard buttons rather than having to rely on the screen, which is VERY NICE! The 6000 has a little slimmer design and classier appearance and feel--those are its main advantages, we think, other than simply being cheaper now that the 7000 is out.
