Hi Anthony and to IIS.
A good and reliable tool for the job would be a collimating cheshire eyepiece which you can obtain for about $89. I use the Orion brand and have found them to be the ideal reasonably priced and good quality tool for the job.
If you check the following link it will explain most or all that you would need to know to collimate a Dob.
It will take some time to master all the reflections that you see but persevere and you will eventually become competent at it.
Good luck and enjoy your scopes.
Cheers Rick
