I made the plunge. After haunting HT stores for the past couple of months, reading this and other forums, I finally pulled the trigger and got the big Sony. I've had a 50" Mits VS-5051 for over 10 years, and it has served me well. But in the age of progressive input, HDTV, DVI and Firewire, its S-Video inputs and 4:3 screen were becoming outdated. The PQ on the Mits is still great, it needs to be aligned after a recent move, but its still looks as bright as the day I bought it. Because of that, I leaned heavily towards another Mits. The new Diamonds are hard to beat, execpt in the price dept. Big $$$. I'm not afraid to spendd for quality, but I couldnt justify the new Mits with the deal I got on the Sony ($3200 OTD with a 5 year in home warranty). Did I check around? Yep. I wanted to like the Sammy DLPs, until I got one for work. SD stuff looks horrible on the 50", and DVD sources still showed the mirror flip in my eyes. I would focus on that and not the overall picture.I really wanted to like the Sony 70" LCD. I have a large viewing room and thought it would fit the bill... until I saw the Sony and a Mit Diamond side by side in a store. The detail just wasnt there on the LCD. Shadows and dark scenes looked washed out compared to the Mits. And there was a noticeable screen door to the Sony, even at my 17 foot viewing distance. And again SD signals fell apart worse on the Sony. I was headed towards the Mits until I found the deal on the Sony WS550. Where? From Sears of all places. Yesterday they had a 10% off everything in the store sale from 7-10am. Plus they will price match, plus 10% the difference off. CC has the set fro $2799, Sears $3299. So I got the $500 off, plus another $50 off, and then 10% of that off. Oh yes, there is a $200 rebate too. Couldnt pass it up. That being said, right out of the box I am dissapointed with SD signals on the Sony. I've got Comcast Digital (Sacramento CA) and I can see alllll the digital artifacts, color tearing, ghosting.... None of which I saw on my old Mits. Perhaps its just that I've blown the picture up soooo big with the 65 inch screen, that I'm going to see these things from now on. That would suck. I'd hate to think that I'd be better off with a smaller set (cuz we all know bigger is better ). Today I'm off to get a HD antenna so I can pull in Monday Night Football and see how the HD picture looks. I'm also picking up a DVI cable for the Sammy HD931 I picked up at the same time. I may have to make the switch to a Dish/DirectTV feed for good SD. Any thoughts?
