It's up to him, but if he did have extra leftover money from buying a 'more powerful one', why not have cheaper and safer ones. Maybe for showing friends who wouldn't have protective glasses on for those 'more powerful ones'

For a starting laser there's this: Green and Blue/Violet Laser Pointer Combo SALE US SHIP - eBay (item 120590001513 end time Aug-28-10 11:33:09 PDT)

It says it's rated at 5mW but many of the LPF members have many of these from the same seller and say...

I just hope they are as good as you wonderful people say.
I won't have a measuring LPF though =(
I hope they're both steady at least 50.
Well, if you wanna build, there plenty of build kits Jayrob does and he does the driver settings for you, 'Hot' option.
and he has plenty of other options that come with his kits.
