Hi, and welcome! If you ever decide to build your first laser, check out the tutorials, helps, and repairs section! I also have a great thread on it in my sig (a bit outdated, so do some reading, but the general idea is still the same).
Welcome! I hope you can find our community helpful and open to answering your questions after you've done some reading. Don't know what you're looking at? That's alright. None of us really do anyways.
thank you spyderz20x6 and meatball! i've been reading mostly, safety and gear.. very interested in finding my first laser.. excellent source of valuable info here..
