Don't bet on that yet.
I always assumed I could collimate my scope and it wasn't a collimation error. More than once it turned out to be.

The laser alone can give you "many good alignments" for
different positions of the secondary. So you think you're collimated then you stick a cheshire in the focuser and you go
. The laser alone will get you into a whole world of troubles. You need to use a combination of tools to collimate, the cheshire or cross tube being a bit part of it.
What I try to do is go on a bright star or light source and look for reflections in the glass of the eyepiece or barlow. Checking the alignment of the multiple reflections when the star is dead set in the center is a good indication of which way to shift tings too.
