I'm really worried to touch any buttons when visiting that page on eBay!

I'm convinced that his auction will cause rings on the water, increase the interest of the bike, prices on bikes and parts. I see here in Sweden, prices on good looking CB750 K0-K6 has doubled the last 3-5 years. Good thing about the increased interest of CB750 is new parts coming out on the market, NOS such as really new.
It's very popular to find a good bike and repair it back to new OEM std.
