Malcolm, the little brass-mounted laser units are available from Maplin here in the UK, at about ?11 (add your own switch and 3v power source). The stock number is LE07H. Not as cheap as the US Dollar Store, but maybe worth a look?

A much smaller centre finder can be made by removing the laser diode and mounting it at the end of perpendicular crossed flexures, rigidly mounted at the other end. Only two adjusting screws are then required, set at 90' to each other, giving independent X and Y adjustment, as the non adjusted setting screw slides across the flexure as the other screw is adjusted. The lasers in the cheap laser levels have push on push off switches and brass mounted laser diodes rather than PCB mounted diode. This has been on my 'to do' list for two years.

Got it together and almost calibrated tonight:
Under temporary working stuff - First entry: first prototype.
Initial results are encouraging!
Ended up having to bore it out more since these $1 laser pointers do not
have a vaguely centered beam.
Kinda pleased. Will sit down and finish the calibration tomorrow, was
kind of worn out tonight. Getting it close was a lot easier than I
expected it to be.
Take care, Vikki.
