You can use simple steps and low cost collimation tools to bring collimation within acceptable tolerance and have great views at the eyepiece but good collimation knowledge is required.
On the other hand, with more expensive collimation tools and great collimation knowledge you can perfect your collimation.
Perfecting collimation allows your scope mechanical imperfections to use whatever collimation tolerance your scope has. That is, starting with perfect collimation the scope will remain within tolerance as temperature change and is you move the OTA around.
Everyone should make their own decision on what collimation tools to buy and which collimation method to follow. After all, this is only a hobby.
