Can anyone think of another product that only has a 6 month warranty ? I can't.
I offer 1 year for parts supplied... 3 years if i make and install.
6 months suggests a lack of confidence in a product to be quite honest
How much warranty did new Bally/Williams have ? You will probably find this has always been the standard warranty for pinballs due to them been sited more than a lack of confidence in a product.
