That is very true. You are not paying for the sponsorships, ad revenue, and corporate CEO salaries. No thousand dollar hammers here, just quality products. The SPI primer and epoxy is about the same price as what I was paying from a "name-brand" company, but the quality is much better. I don't know all of the chemical formulas or do corrosion tests, but from what I can tell I am very happy - ease of spraying, excellent sandability, and a very adaptable product to whatever I am trying to accomplish. One of the biggest advantages to SPI is their customer support. Quick to answer any questions and very fast shipping...I get my order in two days.
That said, I would probably kill a kitten for a 100K paint booth.
