I agree with Magnus, I'd be a bit afraid of older time periods due to the lack of modern medicines and, for instance with Ben's situation, if you got an unlucky lot in life, man, you were just plain screwed. At the same time, I would love to go to work by driving a horse-drawn carriage down a tree-lined trail, instead of hitting the 6 lane freeway at 75 mph. People also tended to have morals and honor - they didn't just lie to each other for no reason, sleep with everybody just because it's fun, etc. Well, at least in my idealized view of the time period they didn't - but it probably holds somewhat true.
That being said, I guess 1897 would have been a fair pick. You didn't have indentured servitude, persecution of witches, etc. while you still had all the simplicity.
