is there anything particularly "old" about these lasers ? what exactly is cni referring to, is it the type of diode or the casing? im in the market with around 225$ish and ive read the review section quite thoroughly but i cant make my mind up. Im not sure if sticking to pointer style (novalasers etc) or a little bigger (dealextreme 200mw) but use more expensive rarer batteries. btw what is the battery life on those cr123a's and the 18xxx ones compared to aaa ?
