Electronics again

[CHANCE1234]

I have searched through most electronics posts on here and I have a few questions. Has anyone used the Garmin GPS MAP 3005, (it is a stand alone chartplotter)and if so what do you think. I have seen advertised prices online for $719, and then they offer a $150 mail in rebate through march 24th. Also I have an older Sitex bottom machine that worked well before. However in the process of replacing the t-top with the doghouse, the transducer wire got cut, and I lost the powercable. Does any one out there have these they would be willing to part with. Or does anyone know where I can get the replacement power cord and transducer/wire. Thanks for any ideas.
