Hi there! I am quite new to powerful lasers, and although I've owned a few 10mw s in the past, I don't have much real experience in DIY lasers. I have decided to try and build Styropro's 160mw pen laser build, and I was told to come here and buy the chrome leadlight pen host off of you. Firstly, I would like to request some pricing info if you are still selling this host, and secondly, I was just hoping for some advice on the components for styropro's build. I am planning to order the Osram PL450B diode in copper module from DTR's laser shop, and I was wondering if you could recommend a suitable driver - as I can't seem to find the Microboost Drive online... Also, he did mention that he changed the current to 280mA - so it would have to be pot changeable. Also, what is the switchboard, and does your pen host come with one?
