highpowered pen builds

anyone wanting to build there very own highpowered pen??? i have been converting all these old 5mw pens i have laying around into highpowered units tks to wlaser...u can purchase 100, or 150mw modules from them for 40.00/60.00....its simple but fun process of taking apart 5mw pointers(without scratching unit) and popping in a 150mw module...some pointers may need alittle grinding of the threads at end so host can slip on...some of the apatures are alittle bigger and there is no grinding at all ....ive build 10 of these and sold most with no problems so far...most are way above spec. i really thinks its just the fun of tearing something apart and making it much better... having a pen self built to call your own so much fun....i like these better than opto. pens and they are a fraction of the price.. if anyone needs more details on build just pm me tks..
