I have been looking for a decent cross line laser for my high speed PCB drill to come. DX had model (200)5982 which seems suitable:
Red Laser Module - Adjustable Crosshair (3.5V~4.5V 9mm 5mW) $2,97
According to my lab PSU it draws about 20 mA at 3.5V, 25 mA at 4V and 35 mA at 4.5V. Cross has good visibility in bright indoor lighting. They claim crosshair is adjustable, but there isn't any easy way to focus. This one has. Anyway, this is quite small laser in brass housing.
