I was in the same boat as you tony. Lowrance has a elite 7 dsi unit with all the bells and whistles. Lowrance unit with great features that won't break the bank. GPS with newest mapping, down imaging, and sonar. Packed into a very viewable 7" screen. For around 600 bucks. If you get a chance go to BPS or cabelas and check it out. They have a rebate promotion going on now to.Good luck
