Hands down the Garmin GPS 741XS/18HD radar bundle. I bought on sale a few months ago for $1,899.00 doen from $2,199.00. Currently on sale at West Marine for $1,699.00. The new model 742xs and 18HD $2,199.00 are coming out so last years model deeply discounted.
Full color chart potter loaded with US maps, Radar interface overlay and depth/fish finder interface. This is a touch screen all in one unit.
Also NMEA 2000 capable.
