Cannot the same thing be said of trading cars every year or two? Or the iPhone six making the iPhone five obsolete.
There are those who want the latest and as a consumer of most of my trains, vehicles and iPhone on the second hand market, I am thankful that the almost latest technology is available to me at more affordable pricing.
Also, I attend a lot of train shows and there is a lot of used HO equipment at huge savings over new pricing.
Happy railroading,
Don
