In my neck of the woods taking a machine for annual check -up is typically about $100.00. Anything more needed , such as a light bulb change...it more ... a lot more . My local wanted to charge $25.00 in addition to the annual check up charge for replacing the light bulb... and that was just the labor .. the bulb was more ... 200 percent of actual cost.
Its one reason I love vintage ... so easy to maintain myself. Alas , I have a love hate relationship with my newer machine.
