Welcome to the foums. Be sure and spend some time checking the safety posts out and invest in some nice laser safety goggles if you plan on getting anything of power (they say 5mW, but depending on your use, it may be more... just use common sense and do your research). There is a ton of great info archived here that can be found using the search bar... most of the common questions asked by brand new hobbyists are answered many times over and quickly located using search. Have a blast... this is a very addictive and fun hobby. Cheers!
