I have an untested TV-736 modem. The TV-736 does power on, but I haven't hooked up a TV to it to check the input and I don't know the ATV guys around here to test the output. If it doesn't work, you pay return shipping and I'll refund the payment as long as it isn't damaged.
I'm asking $350 for the TV modem shipped CONUS. Other locations please contact me first, extra shipping will apply, and payment will have to clear before shipment. Local pickup will save you $30.
