I first tuned my laser with a perfect collimated cassegrain scope (most laser collimaters are out themselves).
Then after laser collimating my dob, I use the cheshire. After that I use the star method where you put a good bright star out of focus and line up the consentric circles. This does take a bit of practice but easy to learn how to do. A nice medium to high powered wide field ep can help too, changing powers between them till you notice stars having comet tails - then adjusting the collimation screws till the stars are all pin point (dont do this unless you have really good seeing).
Hope this helps - anybody got better sugestions I too would like to read them as I myself am still only a noob (got my first scope in 2005) and still learning.
