I don't know if it's they are sick of them.... Parts are pretty hard to come by for a lot of them now.
If you don't have a bunch of donor rigs, you can't get some stuff. And even if you do have 10 donors in the back room, that's only 10 repairs for a common problem where parts are unobtanium.
It's easier to keep a 1950s Johnson on the air now than an early 80s ham rig in some cases.
You live where I do, you better know how to fix your own stuff. I can't imagine the cost to ship say a 940 to the states and back. I brought all my ham stuff here as carry on via American Airlines :0
