I am not exactly new to LDDB, having started an account c. 12 years ago when I was given a Pioneer CLD 1070 player. I've built a collection nearing 300 laserdiscs, the 1070 is still going strong, and I just reactivated my account to participate in the forum!
Last disc watched: ABBA in Concert. Released right after their 1979 tour, still offered good sound and picture (there was a bit of snow/rot over the last minute/end credits but no biggie). The glam rock costumes are a bit hard to take, but their music is still timeless!
Last discs bought: Actually found a used LD shelf at a local Half Price Books, walked away with Ghost (widescreen), Urban Cowboy (widescreen), and Harry Connick Jr.-Singin' & Swingin'.
Of course, I have a large collection of DVDs and Blu-Rays (and am in the process of upgrading to 4K capability). Hard to define why I like the big, shiny platters. When the player starts to spin, it provides a visceral sensation - like an engine taking off, or a time machine. Yes, I'm watching a still functional ABBA concert recording - made when ABBA was still an active group! How cool is that?!
And of course, the format was way ahead of its time - surround sound, commentaries, special features, chapter skips - we owe it all to these 'dead' discs.
