Agree with the sentiment here. I got my panel from Arcades R Fun and it is fantastic. I have a feeling Jack is backed up with orders because his reputation for quality work is getting around.
I don't think you can go wrong ordering from him.
I just saw you posted that you're looking for a blank panel, though, and I don't think he does those anymore.
The panel I have, incidentally, does not use cams; there are hinges to open the lid up, however.
