I did end up buying from them. I got a Gen 2 HDS5. I am still having some issues with them though. I ordered a gimbal bracket with the head unit. I received the head unit but not the gimbal bracket. I have emailed them several times with no replies. I had to use bungie cords to hold the unit onto my boat when I went to the Rainy River. It also took them much longer than they said it would to ship the head unit.
Right now, I wouldn’t buy from them again or recommend it. I understand sometimes there are problems, but to not respond at all after they have taken my money for a product they never supplied is unacceptable.
