Welcome to LPF
2 house keeping issues!
(1) some members do sell completed lasers, most are kits that you have to do some assembly on.. You have to get some parts from different members.. To avoid the MAN!
(2) please get safety glasses you only have two optical sockets! spend 30+ on a good set of each.. look in the search function of the site for good deals on safety glasses
other than that have fun....
