Hi All,
Dick Anderson at Anderson Lasers in Ohio has several used Argon lasers in excellent condition with low hours including one doing 1/2 watt. He is always willing to take a reasonable offer too. He is also a good guy-no bull from him. If you want an air cooled argon take a look. www.andersonlasers.com. Tell him Phil Bergeron sent you and he will give you a good deal...I hope!
