I've been very happy with my Lowrance LMS320. Nice screen, good
resolution, not too big. Only thing I didn't like was that it has a
remote gps antenna. I used some glue and velcro to attach it to the
top for use in my Kenner center console.

Main selling points for me:
uses insdustry standard flash memory not propietary like Garmin
If you buy Mapcreate you get maps of all the USA you don't have to buy
more key
s to unlock other locations like Garmin.
I actually use it in my Suburban for auto GPS as well.
Compared to Garmin the Lowrance Sonar has more power for the same
$$


Everybody has his brand preferences, I wouldn't consider Humminbird
and the other things like Raytheon etc. seems like you're talking lots
more $$.

A sales feature for Garmin is that it is supposed to work with
OzieExplorer map software if you like to make your own maps from
scanned in hardcopy paper maps although I've found the Mapcreate is
plenty good.

Have fun. I think you'll be happy with either Garmin or Lowrance.
