Sorry to hear about your trouble with Garmin. I have had 2 Garmin 240's and now have 2 Garmin 168 GPS/Fishfinders(older/discontinued models that can easily be had on E-Bay for around $200.00) and love them. They are the older models but do absolutely everything I could want. I only had a minor problem with one of my 240's and Garmin immediately took care of it even though it had been out of warranty for over a year! I couldn't be more pleased.
I tried using one of the smaller handhelds and the screen was just too small for me. The 76c has a pretty good screen for a handheld though.

Happy Fishin'
