good 2nd hand gps units?

I had an older garmin 180 gps on my last boat and it was pretty tough. I was curious if any of you had suggestions for other used gps and or fish finders that you would suggest? Looking for one for my boat project. Thanks. Craigan.

I bought a Garmin Street Pilot III on ebay for 65 bucks, color with bathymetric capability. Works perfect as a backup GPS as it works on bothe external power and AA batteries. saves tracks and works with Mapsource. If you like, you can take it in your car or wherever


Fishing on the bottom is like having sex with the lights turned off. It feels good… but I wanna see it.
Lights On!
