Default Laster with smallest red dot at set distance

Hi,

Firstly I confess to knowing very little about laser modules, but I have an alignment application where I need a very small dot for measurement.

I don't need it to be particularly powerful, but I do need the dot to be as small as possible (0.1 - 0.5mm dot size ideally) at a distance of 2-3 meters.

Are those cheapo 'focusable 5mw red laser modules' on ebay what I'm looking for, or do I need something else?
