Garmin Striker 7sv (SOLD)
It works but takes about 10 minutes for the menu screen to appear. New swivel mount cost me $29, and the GT-21 transducer is worth the asking cost.
Turn it on when you leave the house and it will be working fine by the time you get to the ramp. or just use it for parts.
$85 plus shipping (probably around $15 - $20)
