Only thing I thought of mentioning is the review(s) of the Photon20Vision in MacUser and PC Pro - you can find them online easily enough. Nice looking, especially the desk clamp. Don't have any practical experience of them, hence I didn't say anything when you first posted - figured you would've already read reviews!
(Think I read somewhere the internals are to a large extent repackaged NEC-Mitsubishi displays..?)
