I want to start out with a small cheap build that in the end will be a decent laser that i can use frequently. From there I want to get into the more technical builds but everybody has to start somewhere, my first built was from a "How to video" that used a small diode from a DVD burner and an 650nm 5mW AixiZ laser module. Which I soon found out did not last long. I want to know what type of laser would fit my needs. Any advice would be appreciated
