I have a decision to make and could use this boards advice. My old RPTV (Mitsubishi 50" Diamond VS-50803) went bad on the HD portion of the set. They replaced some parts, but it didn't correct the problem... so Mitsubishi directly offered to give me a Silver Series WS-55313 for $1400.00 or the Diamond WS-55813 for $2400.00. I don't think I can come up with the $2400. So my questions are this... 1. Does the WS-55313 get a better picture than my current Diamond VS-50803... one is Diamond (High-End) and the other Silver Series (Low-End) and I don't want to step down if you know what I mean. 2. If I can push to get the Silver Series Plus WS-55413 and only pay $100 or $150 more... is it worth it to swap up to the Plus model? Is there a huge difference in the picture quality from the WS-55313 to the WS-55413? My big concern with all this is that I DO NOT want to get this new RPTV and find out it gets a worse picture than what I already have. I do not downgrade from what I have currently. I want to make sure it gets a better picture... or why else would I spend the money... AND is the Silver Series Plus that much better than the Silver Series? Thanks for the help.
