Chuckster,
Your interest happens to be one the more difficult reps on a budget. If there were levels of reps, Daytona's would be "expert" level.
I don't want to discourage you from them, but as Andy mentioned, you are better served to wait a bit before you buy one.
The most accurate ones have to be built and are very very expensive. As far as subdials, there are no rep movements that are exact size as rolex.
This is why the compromise on the cheaper ones. I have been around reps awhile, have many fine watches....I found out I wasn't ready for a daytona yet. I do own a cheaper one.
There's just so much to learn and know. The good news is the info is all here at rwg
