It's the same option as between a $$$$ custom boutique bass, or a good, solid, well-made "stock" instrument in the $500-1500 range.
Many feel that a standard production build is all they need or want, and they are right.
Others...Will pay & wait for a Custom build. They're also right!
For the grade of leather used, for the detail & workmanship, the Geezer strap is not outlandish priced IMO. It's not my style either, but that's neither here nor there.
I can list a dozen strap makers whose works are extraordinary and beautiful, and whose pricing can range from $150 or so up to...lots more.
There is a cost involved with their craft in making a good product by hand, just as with instruments.
