I have a Mits DLP that I like, but I have heard great things about the Samsung DLPs, mainly from the guy that did an ISF calibration on my Mits. According to him, Samsung is very good about communicating with the ISF calibrators and working on them via the service menu is apparently pretty easy.
This is not such a big deal for some people, but something to consider when checking out the displays.
www.CIR-Engineering.com for info about the calibration, it is well worth the money.
