Careful if you buy a Samsung DLP. I have one (HLS6187W) I bought a little over a year ago, and many of Samsung’s larger DLP models have an issue where the light tunnel collapses, rendering part of the image dark (not blank — you can still see the image if you get close, it’s just not illuminated). AVSForum has a thread with 1500 posts of people with the same issue, and I personally am waiting for BestBuy to come out next week to repair mine. Other than that, I really like my DLP — saved me a bundle of money for the size (61”) compared to flat display technology.
My 2 year old 56' is, indeed, a Sammy but I have experienced none of those issues ... maybe my 56" does not qualify as a "larger DLP model" like your 61"
