I have had them all,Garmin, lowrance, hummingbird, and raymarine just to name a few. I now use Furuno except for my autopilot, it is Raymarine. I have the Nav Net II series 10.4" screen with radar and GPS and I have a seperate fishfinder it is Furuno 620. I love this set up and works well for me. If I were to change anything I would get the Furuno 585 fishfinder. Its the same as the 620 but a larger screen. The Radar/GPS unit was expensive ($4000 +) with raydome and sensor, plus an electronic compass so the radar can be overlayed the GPS. The fishfinder and transducer was around $1000. I did like the garmin unit I had, it was very user friendly. This Furuno equipment is much more difficult to figure out. I spent days at the dock just going through the manual and learning how to use all the features. I also prefer C-MAP charts over Navionics, C-MAP more accurate and better detail. Just my 2 cents worth on marine electronics. There are a lot of deals out there now on electronics. Check out thegpsstore.com, defender.com, tuppensmarine.com, boe.com, just to name a few, if you know what your looking for you can find some great used equipment on E-Bay. I avoid Bass Pro and Cabelas for electronics, great places to purchase tackle but when it comes to electronics they don't have a clue. One more thing I have a good amount of cash wrapped up in electronics, but I did also purchase a top of the line compass and a good set of charts learned how to use them.
