Why do sewing machine manufacturers quit making parts for older machines?
I understand that companies want to sell "new" products.
However - I am more apt to buy from a company that will stand behind their products for years and years - "If the model I bought in 1980 is still running strong (and I can get it fixed if necessary) - I am much more apt to be interested in the machines available now."
If whatever is obsolete in five years or less - and not repairable - why would I want to bother with it?
