These things are a dime a dozen. I got several of them for free.
Sun rebadged them and put them in Sun casework and put a Sun video plug on the back (along with the VGA one) and sold them for UltraSparc's. As the UltraSparcs get junked/sold, the monitors get junked/sold too. People don't realise these work with other computers!
They get thrown out a lot for this reason too: A bug in the software causes the screen grid voltage to go off the map, and the display is blinding bright with the brightness control turned all the way down. The one I am using on my A3000UX right now was like this. $50 on a cable and software and I am able to fix the monitor whenever this happens.
