I'm about to buy the 60 inch Samsung DLP. On Samsung's website, the model number shown is HLM617W but at P.C. Richard's they only have model number HLN617W which they assure me is the exact same thing. They said the N designation refers to the sets sold by their stores. Can anyone verify that's the case and that the M designation doesn't refer to the most current model coming out? At this time I don't want to get last year's model. Thanks in advance.
