Mitsubishi is currently the only company still making dlp tv's with the smallest size in production being 73 inches. You may be able to find new old stock/used floor mode/gently used/refurbished units of the older 60 or 65 inchers still for sale.
I think the picture quality of the mits sets is really good when calibrated properly, though black levels can be somewhat lacking compared to plasmas, and the picture at least on my set looks remarkably better in the dark, and they do not suffer from motion blur or burn in. Most models require a bulb replacement every few years and some people have been known to see rainbow type artifacts when viewing (more common on older models as far as I can tell). I do not know any thing about the samsung model you posted, other then that a quick search tells me it is a 2005 model and is lacking in common features available on more modern sets and not being a 1080p set is a turn off for me.
I don't need snobs to tell me how to think, thank you!
