Hi Ric.
Welcome to IIS!
I don't use a laser, but have heard that to use them effectively, you have to ensure your laser is collimated! The easiest way to do that is to put it in a v-block of wood or similar, and project the beam against a wall. Turn the laser and see whether the beam stays put or moves with it.
I use a sight-tube/cheshire combo, and I find it great. It's all i've ever used in 2.5 years. I got the longer-tube one (not the short one) - they're about $60 or so but will last a lifetime.
I have however, just ordered a set of Catseye collimation tools. I'm at the point now where I want to know my collimation is PERFECT, not "close enough", and so these catseye tools will help me achieve that. Not exactly cheap but i'm hoping they'll be worth it.
