I have come across a Coby Digital Converter Box that I have no use for.
It powers on and appears to work but I did not hook it to a TV to test it completely.
A quick search on ebay shows this model selling new for $45 - $50.
I expect shipping to be around $5 so make me a reasonable offer above that and it's yours!
Feel free to ask questions. You can pm me here or use the email at my call lookup.
73 and thanks for looking.
