I went to Chicken Alley today because I had $20 store credit.
I walked out with an A1407 27" Apple display for $20, because no one in there knew how to turn it on. It has the old squarish magsafe power connector (which works with Mum's 2011 MBP, much to her surprise) and with a Thunderbolt to USB-C adapter, I can it get it to work with my M1 MBP. It's quite a display, 1440p, LED backlist, Apple color accuracy. It also has a hub function (wired ethernet, USB 2.0, FW800).
I also picked up an Apogee audio interface and a Sunpak speedlite. More on those later. MV life is a trip.
