Ok, much as I suspected you are jumping the gun a little.
This website here
http://www.astro-baby.com/collimatio...on%20guide.htm
is the guide that I used. Don't know if it is the gbest but it worked for me!
Notice it doesn't actually talk about using the laser. I follow the procedure in this guide every few months and use the laser each session to check the collimation and make fine adjustments to the mirrors. I also will check with the laser during the night if the temp has changed by a fair bit. All the parts are metal and are going to move as the temp changes so I have a quick check now and then.
Would also recommend buying a complete Bobs Knobs set, makes the whole process MUCH easier!
