I have 1 Lynx Express v4 controller that does not work properly. It is completely built, but channel 6 and 7 do funny things, and the LED display does not work.
I am selling it for $30, and that is shipped to your doorstep.
This was my first controller I have ever tried to solder, and it just didn't work out. If you look at the back of the controller, you can almost see where I had an old soldering iron and where I soldered with the one I use now.
I have not tried this out with the dongle, but I have ran the test, and everything looks good with the exception of channel 6 and channel 7 and the LED display.
I don't have to time to mess around with it, so if you have some time, and resolder it, or something like that, then you got yourself a nice controller.
If you are interested, send me a PM with your PayPal e-mail and we can go from there.
I will get some better pictures up tomorrow.
Thanks,
Jesse
