Wondering which laser to buy???????

I was looking at the blue spyder III laser form wicked laser for $300, the 150mw waterman series green laser form warnlaser for $200, and the 100mw S3 spyder fuison green laser for $200. Which green laser is better, and is it worth spending the extra $100 for the blue laser. I was also wondering how many miles a 100mw-150mw green laser beam is visable
