I like his tool tray full of bunches of different handles and tips.
I like the fitted disc that he puts into the gas cap neck.
And he has one of those fancy-expensive tank holder jigs. And, of course, the light bar.
He has a lot invested, so I can understand the $535 price. But, I can't see anyone ever paying that much to repair an XS650 tank, which being 40-years old would probably need new paint anyway.
