not a 'how do i collimate' thread, i'm more interested in what tools people are using to check/adjust their collimation and how accurate they think the results are.

i've always just used my cheshire but i've never felt that i absolutely nailed it, especially when it comes to imaging.
i did use a laser collimator for a while but in the end all i found it useful for was checking the secondary, it got me in the ballpark for the primary but i always needed to tweak with the cheshire.

whats your angle of attack? lasers, cheshires, sight tubes, autocollimators, barlowed lasers? and how confident are you that your getting close to perfect when the jobs done? (example: i know my collimation varies a bit with my 12" because i can see the difference at the eyepiece occasionally)
