Boris marine electronics. He has new, used, and refurbished and many that people just don't pick up. I buy all my stuff from there and he stands behind his product and can repair them also.
I teach school and am on a limited budget and he's always done me right. Many times if its unrepairable to original quality beacause the parts are no longer available, he upgrades it with new available parts and charges the same.
