DROs are nice, but definitely not necessary for just about everything you can do on a machine. As others have said, even with the DRO, a proper bore will require several starts and stops.
The fastest way will definitely be to get close and then ream. It will probably give you decently repeatable results as well.
We are fortunate enough to have a set of bore micrometeres at our disposal. They are extremely nice, and extremely expensive. We only allow experienced machinists to handle them and use them. They do make checking bore sizes a breeze though, and in our experience, are extremely eaccurate.

Why is it whenever you tell someone there is a million billion stars in the universe they believe you, but if you tell someone that the bench over yonder has wet paint, or if usfirst.org comes up as the 1st result in Google people have to try it for themselves?
