Welcome to IIS Ric
I have both a Cheshire eyepiece and a laser collimator. I hardly use the Cheshire now as I mainly use it to centre the secondary and once that is done it hardly ever needs checking, maybe once a month at the most (haven't had to change it in over 18 months). I use the laser to ensure the secondary is hitting the centre of the primary, always OK as it is locked, and the beam is returned back to the secondary accurately, usually extremely close and only takes a tweak of the primary screws to adjust.
My answer is that both have their jobs and, considering their cost, they have a place in every kit.
Cheers
