Welcome!! Before you get your laser delivered, make sure to have a nice pair of at least OD4 Laser Safety Glasses first! You WILL go blind burning stuff with a 7W laser without glasses, no lie! Honestly I would recommend starting off with a 100mW laser, then go to an M140 diode, then maybe get yourself an NUBM44 diode laser. If none of that makes sense to you, please browse the forum and check the rules and stickies, they are LOADED with information, have fun!!!
