I've looked at jet lasers and sanwu. I have a 405nm sanwu. I like this laser and I'm considering buying a new laser at this 462nm wavelength maybe from them. But looking at the other company and reading over some posts of JT's lasers I'm inclined to maybe buy from them. The price of the JT standard unit is less which is good. The overall quality also seems as good as sanwu. If anyone has experienced with both companies at this wavelength chime in with your thoughts.
