I'm thinking about buying the S1 Sonar Lunar from wicked lasers its 200MW purple laser for only $90 however then I saw the E1 Executive Pulsar which is a 200MW red beam for only $50 is there any difference in power between the two or is it only color? Also I live in the states I am not so much concerned about if I "should" own it but if I bought would it come scaled down to 5MW or would I get it as its full 200MW?
