I have a Sega 29E31E-B 29" 31khz monitor for sale.
I purchased a Net City cab with the monitor in but I have just swapped it for a 15khz monitor so I no longer need it.
The monitor has some Initial D screen burn which is noticeable but its not terrible. It shows up worse on a light screen but on darker colours you can't really see it.
Couple of pics of the monitor before I removed it:



I have removed it from the cab and transferred it into a spare 29" case to keep it safe.
Heres's a couple of pics of it in the case and running a DC though a VGA box:



The monitor has a VGA connection and you can connect a PC/DC/Xbox 360 straight to it running at 640x480, all of which look awesome.
Apart from the burn its has a great picture and is a good monitor if you are after a large 4:3 31khz monitor.
Asking £60, pick up only (East Midlands).
