If you are new to lasers, don't build if you are on a budget. While building may be cheaper for experienced guys, it is not for a beginner. You will spend more on trying to find the right stuff and from whom only to find out that you needed a thingamajig instead of a whosi-whatsit. That is where it gets exoensive. I would have saved myself a TON if I had just built mine differently to begin with. After it is all put together, THEN you need to file for a variance and if it is not built to specific safety specifications.... more money is needed to make it so! So, for a beginner, buy a pre-built and safety certified projector. Then you can learn how it works and build your own in the future because, you WILL want more! :P Lasers are dangerous to pocketbooks as well as eyes!
If you're the smartest person in the room, then you're in the wrong room.
