First off forgive my rant, which isn't so much about this TV, as it is about evolving TV technology. If you make it to the end of my post, I applaud you.
I bought this Sharp TV at Sam's for multiple reasons. One to go bigger than our 4 year old living room 61" Samsung HLT6187SAX LED-DLP. Second, so we could move the existing 61" into the bedroom to replace a huge 7 year old 65" Toshiba CRT HD RPTV the Sammy had replaced for something with better picture quality. For the record the 61" Sammy in the LR did not "need to be replaced". That thing still has a perfect picture. So much so that new TV's are pissing me off. It almost seems we've taken 2 steps forward and one back. It used to be mainly about black levels and picture quality. Now we have freaking DSE and SOE issues. I curse society for pushing us into super thin hang on the wall LCD thin TV's with more issues and killing what could have possibly been even slimmer RPTV's without these new issues. Form over function is the new norm I guess.

It seems all of the TV manufacturers these days want to tout first how thin their TV is before they even talk about advancements in picture quality.
I've bought and returned some smaller 42" or so LCD's and plasmas to try and replace just the old 65" in the bedroom without changing the living room 61" Sammy we've loved over the past couple of years. But, after getting accustomed to a 61" plus TV in our home, anything smaller has become unacceptable to even my wife. I also couldn't see spending more money than a 42-46" just to replace a bedroom TV. So, I bit the bullet after only 4 years with the 61" Sammy I love to spend 2k and buy the Sharp.
I've had this Sharp TV for a little over a month now. Out of the box I was mostly happy. Then I used Jason's Movie settings from March and was blown away by movie quality and for that matter watching the news. However the one thing that has set me off is watching hockey.
Overall I'm not a big sports fan, but unfortunately in this new LCD/dwindling plasma world it seems I'm really screwed being a huge hockey fan. The DSE/diamond whatever you call it is driving me nuts with this set. Jason's most recent Movie settings from April seem to make it worse, although cranking up the backlight seems to help. I finally bit the bullet and tried the Game settings and that has made it a bit better for hockey while making everything else look worse. I shouldn't have to switch picture modes. Call me lazy, but I believe any TV should have a decent middle ground in one mode without extremely blatant issues.
I'm finding it really hard to justify a 2k purchase for "any" new TV when I've read now from various places that almost all LCD's exhibit some bit of DSE or SOE. After some initial not so dramatic forum seeking tweaks 4 years ago my 61" Sammy LED-DLP looked awesome in super bright or completely dark rooms and continues to look that way today.
I bought this TV at Sam's, so I have 90 days to return. I've pretty much decided as of writing this that this set is being returned. I'm beginning to feel like I should just pull the old 65" RPTV HDTV out of it's current spot in the garage, put it back in the bedroom while moving the 61" back into the living room. and then saying to hell with LCD/Plasma until one of the two TV's dies or things get better with new tech.
One last note. Thinner and newer doesn't mean more power efficient either. Most of the LCD's and especially plasmas I've tried over the last couple of yeats, including this TV, suck more power based on my findings from a Kill-A-Watt meter than either my 4 or 7 year old TV's.
