Thank you all for your responses. Great info here.
This is the kit I bought from someone on craigslist: https://www.highpointscientific.com/apertura-ad12-12inch-dobsonian-telescope-ad12. I have all of these tools here including the laser collimator. Also I do not wear glasses. I didn't really have an initial budget in mind, just wanted to get the feel for what the recommended ones cost. I'm the type of person that likes to try to only buy things once if I can afford to, so I don't mind shelling out some cash on something that I will keep for a while even if I have to save up (It's ultimately cheaper this way). I see what you all are saying about using eyepieces over Barlows. Another reason I was looking at getting a Barlow though is to attach my dslr to the Dob. I understand it isn't great for long exposure photographs but as a photographer i'm naturally curious with what I can achieve haha and maybe eventually I will upgrade to a refractor with a tracking system. But that is far future, I plan to use this scope for quite a long time.
