My luck for the year: 55" ST60 for $25
I got it from a very nice gentleman who was the original owner and recently purchased a new TV to replace it. 18,000 hours, minimal burn-in. Only issue is that the plastic trim piece is coming off, but should be an easy fix with some cell phone adhesive. It was on CL for a couple months and I'm honestly surprised nobody else picked it up. He even mentioned lowering the price a couple times and still having no interest. Brought a friend with me to help carry it and it juuust fit in the back of my car flat with some towels. Drove like I had a nuclear bomb in the back and it survived fine.
I've wanted one of these late model Panasonics for a couple years now but they never seemed to show up in my area. Plasma displays are just so cool to me, and the final few models feel so well-built and refined as the manufacturers tried their hardest to advance the tech before running out of steam.
