Thanks for all the response to this request. I am more confused now than when I started on prices since there are so many variations of the units with SI, GPS, DI, will it network, used price vs. new price, Chirp, non-chirp. Wow, I need to study more. If anyone has a simple explanation of all this I welcome it. My main needs are an SI with GPS on console of a Ranger Sport R70 (17'). Are the newer Helix units quite a bit faster and better than the "legacy units"?
Keep offers coming, I'm studying and trying to decide. Trying to get the most for my money like everyone else.
