Yes. The leds are gone in the CZ-21. That must be hard for you for sure. You might want to advertise on here to trade a 21 for a 20? Just a thought. Also maybe you can call Felix at Fisher and EXPLAIN your situation. I don't know if they can increase the volume on the machine with some kind of enhancement or not. I can't see why not. If you want me to do some research I will be happy to.
I have a good working 20 with a 8" coil. Great machine. I would be willing to trade BUT, maybe there is a better alternitive like I said. I really think the parts in a 21 are made in CHINA, Nobody will confirm or deny it though. PM me if you would like me to contact First Texas for you. Will be happy to see what I can do.
