I'm looking for a laser level for not much money. I really only need it for, as they show in the adverts, hanging a number of pictures evenly along a wall... or at an angle parallel to stairs.

Every once in a while, I may want to use it to place lights on a ceiling evenly.

I've seen models from $10 to $200.

I really just need it to be straight to 10-15 ft. And I don't need 'self-leveling' so long as the angle gizmo... or bubbles... are reasonably accurate.

I saw one from 'Strait-Line' that seemed to fit the bill.
