The lesson is, I don't need collimator and the chance of need to
re-collimate is very low.

A good point but you apparently didn't look at the instructions on the
Kendrick web site. If you use a laser collimator on an SCT in the same
manner you would with a Newtonian, you will most likely badly decollimate
your scope. Check out the Kendrick site if you're interested in the correct
way to collimate an SCT with a laser.

As to your point, the fact that my scope almost never needs collimation
since I don't move it very often, is why I've sold my Kendrick laser.
However, I may buy another in the future once some other projects are
finished. It's handy to be able to achieve a really good collimation when
the weather doesn't allow a good star collimation.
