Help the decision on a Fishfinder is keeping me up at night.

Hey guys new to the board, but I have read a great deal of the posts and appreciate all the great information that is available. Here is my question I have narrowed my selection down to three models.

Lowrance Elite 7Ti TotalScan unit 749.00

Lowrance HDS7 Gen2 Touch with the Structure Scan Transducer 799.00 with all rebates and coupons.

Garmin® echoMAP™ 73sv Combo with LakeVü™ HD 499.00

All have mapping, all have structure scan. I am leaning towards the Elite TI but the Garmin looks like its pretty good for a 250 savings, just missing the touchscreen. As far as I can tell the only difference between the Elite and the HDS are networking ability, is that accurate. Is the touchscreen worth 250?

Any insight would be appreciate.

I really like the touch screen
I have hds9 and elite 7 TI

Thanks, Is there much difference between the hds9 and the 7ti other than the screen size. Thanks for your input, I think that the touchscreen would be nice too.
