Ok....I went to the store and had them look up all they had.....no ps that is 12V and more than 1000mA. Someone posted that they did at one time....but that must have disc. the item. They do have some regulated ps for 39.99, but only has a lighter adapter input...you can buy the cable to go from the monitor to the regulator for an addl. 5.95....but it seemed to be too much to accoplish the task. I would rather have the original, this way if the monitor dies...you can get it repaired under warranty, I think they might argue the fact that you weren't using the proper power supply, so warranty is void.
