+1 for Lowrance HDS. Go for Gen 2 or newer, the first generation doesn't work with a lot of the newer and forthcoming products.
I have an HDS Gen2 touch and it is excellent. The Gen3 will add chirp and wifi, which can be added to gen 2 for a $500 unit (sonarhub) and a $200 unit (WiFi-1). All depends on how important those add ons are.
They will soon be releasing an outboard autopilot at $1000 all in for hydraulic steering.
As I've posted on other threads, I've been lucky enough to outfit several boats at work with complete systems, and have a very new Furuno setup, and a very new (but not the newest dv era) Garmin setup. I also have a new Humminbird unit with 360 scanning sonar, which is cool, but the lowrance spotlight scan seems like a more cost effective tool.
With all this info, when I went to replace my electronics, I didn't opt for any of the gear I had at work, impressive though it all is. I went for lowrance HDS Gen 2, simply because it seemed to have figured out all of the little things that bothered me on my work boats.
Add to that the insight genesis mapping tools, and ability to make your own high resolution basemaps (I run shifting tidal channels, so seeing their movement is a big help when the nav markers don't keep pace with the shifting sand!), and generally geek out over actual first hand imagery of your favorite fishing spots.
I would add that I have no affiliation with any of these companies, and like all of their stuff. But for what I like to use my own boat for, the lowrance hds gen2 gear was the best fit I could find.
