I have their top model/tablet and since I'm getting older, larger is better to me. Plus having the super motors is a plus too. I had a different robotic system before going with IQ and the screen size was so much smaller. Other than operator error from time to time, I'm loving this robotic system. My idea is..........get the best you can for what you can afford. I don't plan on upgrading anymore as this is just a hobby to me. I'm using mine on an Innova too. True $1,000 seems like a lot for 2 inches but if you remember when the TV's started coming out with larger screens, did you run and get one? When our PC monitors started coming out with larger ones, did you rush to get one? That will answer alot about yourself too. No I didn't rush for either one myself, kept using what I had till it died but now glad I have the larger screens to watch TV and to view online with.
