Just like every other collectible, there is an industry there to service the collector. I'm just immensely thankful that the Internet and ebay for that manner, has enabled finding what you need and if you're patient get it at reasonable value. Imagine if all we had to rely upon was a version of Hemmings?

Also, it makes bike collecting self funding, as one of the outlets to turnover unused parts or reconditioned bikes.

I have bought and sold lots of items via ebay, from Pentium Pro motherboards to cast iron Kohler sinks.

And while I patronize the neighborhood hardware store where Clint Eastwood shopped, I have to turn to the Internet when fixing an appliance; diagnostic advice, exploded parts diagrams, and parts. I've replaced a SubZero fan, Viking range igniter, Bosch dishwasher switch, Grohe faucet, Whirlpool range gas regulator, and Whirlpool ice maker, all with the help of PDFs, ebay, and Amazon. The appliances in fact were bought used, for as little as 6% of current discounted retail.
