i love my viper!! and yes glenn can get them cheaper, but DL sells "cherry picked" lasers from CNI so you are sure to get one overspec, DL charges $300 for a 125mW viper with $18 to ship to USA. DL is a tad more expensive then glenn's GB because they pay more for them, and need to make some profit(they are a store front afterall) but you can be assured that EVERY DL laser will be over spec, some a little and some a lot! my viper peaks at 180mW!!! and puts out a cont of 150+mW. now isnt that worth an extra $40, plus as mentioned above you get DLs excellent customer service plus a warranty!
