@Chris Cables: Plenty to appreciate. The Sony Metal XR was/is such a nice Type IV. At one time they were the best affordable Type IV you could buy as NOS. I bought a number of cartons of them - notably, from our own @Web Police. I think John was selling them for about $2 USD per cassette.
The angry-face Denon MG-X is due to all the attention given to the likes of the Maxell Vertex, Sony Super Metal Master and TDK MA-XG. View attachment 81958

Everyone knows it was the MA-R that started that "sexy shell" trend... I still remember seeing the ads for the first time in the magazines and thinking that was some Star Wars technology right there.
