Quoted from PinMonk:Yeah, Stern had essentially 100% price inflation in less than 10 years, and the quality is reduced in that same timeframe.
He paid $3840 for his Stern IJ (including shipping) in 2008. A 2018 Stern Pro costs $5400 shipped. So a 41% price increase in ten years. According to the Bureau of Labor Statistics, inflation is responsible for a 15% increase in prices over that same 10 year period.
