The red one is pretty good, if you want a burning laser, you'll get a serious one. Running off 2 CR2 rechargeables puts normally more than 200mW. look in the red lasers subforum for more info they call it the "red dilda" due to its shape
I would not buy a green laser in a pen-sized host sold for more than 50-100mW, 200mW of green would require at least 1W of 808nm pumping, I really doubt in that laser you'll find one. If you want a noticeable green laser, go for a "true" 30 or 50mW, or, if you want to spend more, look at other sites or different sizes, like cr2 powered ones.
