I miss the Ace hardware in my old city of Costa Mesa CA. They had taken over the original hardware store, run by a family. What was nice was that it basically stayed the same... even the free popcorn machine at the entrance! Well until the stupid city regulations told them to take it away, after it being there literally 50 years.

GREAT people there as well. Then the lease amount went through the roof and now it's an empty old building.
Can you post one photo of the machine itself and one of the inside. My CEI has all the controls inside on a panel.
