Yea Phil these are super lasers, simple to work on and they lock in to SLM mode with no problems! I regularly swap out the diode, clean and realign the optics and correct the output beam to be more holography friendly.
With the correct diodes installed these units easily put out 50mw plus ! I would suggest if you send it overseas dont include DCpower supply (5VDC @ 8AMP) and no heatsink, and should cost arround $50 to ship .....
