Had a Master and now a Iso Tip-butane models. Nothing but problems with both. Former replaced twice, latter now on it's third.

Is there such as thing as a reliable and decent cordless soldering iron? As I also perform some automotive I do not think a soldering station would be practical.

Suggestions please?
thank you

 

This is my personal opinion:
The only cordless soldering iron that I've used that was worth a damn was a butane model. That said give me a real iron anytime.
