Not that there were satnags a few years ago... but at least it's better than it was a few years ago, re spares / replacement parts. I remember discovering what the offending component was on many a failed electronic gadget only to find that I couldn't get a replacement. At least now I can put the component serial number into google and find the spare somewhere in the world. My old reel to reel was a clasic example, I got rid of it in the 90s because no bugger knew what I was on about let alone have any idea where they could lay their hands on the parts I wanted. I wish I still had it because I could find the spares now easy as circumnavigating deep packet scanning.
