I'm in the process of selling all my boxed postwar stuff and some boxed MPC. Just keeping enough PW & MPC to run and enjoy.
Never got past William's level stuff and a few PS-1 engines (so cheap they can be doorstops).
Reading the forum threads kept me from the electronics stuff. I don't know of a dedicated train store within 1000 miles of me. So getting repairs would also be a pain. I enjoy seeing it on layouts at train shows, but I couldn't justify that price/heartburn ratio.
PW is so dependable and repairable. And I enjoy the smell of ozone, smoke pellets, and hearing the clackity clack that lobster claw toys make when running on tubular track.
But that's just me
