I have 4 Lynx that have power in/out cords and have been used so they work. I have two Lynx Express Ver. 5 with input power cord never been used. Also the Lynx dongle. Dongle gone!
I also have around 24 of blue, red, green and clear Incandescent strings. Not sure if the shipping is worth more than there cost new tho. Free if you ship.
I haven't sold stuff with paypal, etc before; but that is what I would use.
Lynx and Express for $50 each . You pay shipping.
