I am also aware of people who have spent 100s of thousands of dollars restoring a '60s muscle car that when new cost several thousand dollars and later selling it for way less than the restoration cost... My point was just to stir up some commentary on the insanity of doing so... My Edison Standard comparison was based on the amount of scrap metal you would get for $5000...

Do whatever you like... If that is spending $5000 for gas caps or $1700 for used oil cans, go for it... it still equates to insanity...

Like I said, our hobby seems nuts sometimes, but at least you get something to play music on when the electricity fails... Gas caps or oil cans are no use in a power outage...
