I bought an rx65 for $60 because the guy thought it was broken when the service required light came on. I called Bel and they told me as long as there is no water damage and the serial number is intact they would fix it for $59.99 and put in the latest software. There is no water damage and the serial number is legible so......$120 for an rx65.
The guy didn't want to mess with it and got another detector and was dumping this one cheap. It is about a year old according to him, but as long as they update the software I really don't care how old it is. I will wait and see what Bel says when they receive it.
Worst case I lose $60.00, but I took a chance. Would you have done the same thing?
