Amazon Marketplace has one new Mits 60 inch 1080p, from a new and unknown seller.
I'd bite the bullet and get a 73 inch, since you'd probably pay as much to get the last 60 or 65 inch models left, the features are more advanced, and you will enjoy the more immersive picture. I'd try to get one from a brick and mortar store near you. The only downside I've read about these are sets damaged in shipping...and I would get an extended warranty.
65 and 73 inch Mits DLPs seem to me to be the sweet spot for these sets, with my preference being the 73. Given the wattage and light output of Mits' 150-180W bulb, these sizes are bright, with pretty even illumination across the screen.
