abarkley, I have a Elite 7 HDI that I really like. I have only used it 2 times and am still learning. Try to go somewhere and see it on display and maybe get to play around with it. It has some cool features that I like. It has a 7" screen, really bright, GPS, 2d and DI. You can see any screen or a combination of any screen or all three at once. The screens are pre set and it is easily adjusted. I really like the triple screen that can be set to over and under or side by side. The DI is new to me , but I like it. It does not have SI, but not a problem, Hope this gives you a start on your research and good luck with your choice.......crappie1133
