Collimation, HOW TO??

I believe I am collimating my Newt correctly but have a feeling that I'm not "precisly" accurate with my collimation skills. I was wondering if a Cheshire eyepiece might help or are they a waist of money?
I've learned to use "star tests", as well I own "The Backyard astronomer" by Terrance D., which has an excellent discription of what should be done. But collimation seems to be the type of thing which is better shown to parson, rather than have them read about it.
It would be of great help if someone would please guide me to a website which has a HOW TO section, or just tell me their personal struggles with collimating Newts, because I feel as though I'm shooting in the dark with my alignment which is just about the worst thing any telescope owner could poassible feel.
One more question: When you see an "Airy disk" pattern is it when it's out of focus or in focus? I'm unable to see one when it's in focus? Does that say anything??
Thanks again, I woudl also like to thank those fine people who put this forum site together if it wasn't for this site I'm not sure what I would have done if I had to rely on the Astronomy stores in my region!
Clear skies,
George C.
