I am looking to buy the SF501B from Sci-Fi Lasers. I am trying to decide what power to get. I have never owned a blue laser nor have I seen one in real life. I have a 50mW 532nm from Ledshoppe that I use for night-time demonstrations along with star-pointing. But I would love to get a blue one to increase my collection. My main questions are how visible is the beam of a 1W blue laser compared to a 50mW green laser? And would it be worth it spending extra to get a higher powered laser (1.5W-1.8W or 2.2W-2.4W) instead of a 1W?
