Don't be intimidated.
I needed a large beverage and a lie-down before I attempted my first collimation on a 12" GSO dob.
Using an Orion Laser jobbie it was done in under a minute!
Can't recommend them (lasers) highly enough.
'Howie Glatter' collimaters are supposed to be the business. Accurate to a 'T' and very well made. They are however around $200.
Learning the theory and basics of collimation is only a good thing, but using a laser will help you eliminate any eye-induced errors.
Plus they drive cats nuts which is always fun!
As a BTW - make sure everything is snugged-down tight before you start - focuser, EP holder, mount - otherwise you are likely to introduce flexure into the optical train and your collimation will be out.
G'Luck!
