12 g2n or g3n?

Looking at buying an open box 12 msi g2n or should I spend the 800 more for the g3n si?

I'm going to be running si and maps only

is warranty involved with both? I trust birds...but i sure do like a warranty for something thats electronic thats gonna be used on water. The helix series I believe is pretty much the same....but the G3 is noticeably crisper...not a ton, but it is a noticeable. you also can scan out farther on the G3. I think theres other stuff...but for a goon like me thats basically the difference.

Also the G3N will be able to run the Hummingbird live transducer when it comes out.

the g 3 is WAY better side imaging, the transducer is longer the picture and distance is superior DO NOT buy a g2, in fact I wouldnt buy a g3 if I was buying new I would buy the g4, for the most part the g3 arent even available anyways.

According if you care about live. I love using DI after finding fish on my SI and bopping them on the head so I will probably love the love but its only g3n and 4

Is the primary difference between the Helix and Solix the touch screen?
