OK, here is a mini-review with pics of the DX100mW Red module and driver.
It is a dual driver (Red and Green). There are pots for both sides to adjust. The Red side adjusts from 75mA to 260mA drive current. I had no load for the green side so I did not test it.
Output beam size is pretty wide ~5mm but the divergence seems quite low.
All in all - a pretty good deal for $17 and change!
