I forgot to mention that I did finally end up rebuilding my media rack as I had been planning in a previous post. I replaced the rails with these guys (link below)... not has heavy duty as my old rails, but the standard cage nut system works so much better than the permanently threaded rails I had prior. I would usually strip out my screws half of the time and would have to use a stripped screw remover to get them out typically. It doesn't look much different, so I doubt I'll post any pics.
My AE8000 is still going strong and I am happy to see that it is still Panasonic's latest offering. I will probably hold off until I eventually go 4K (maybe next year or when 4K sources are more available).
