Wedding photography in 2009

As some of you may know, I cut my teeth on wedding photography, I've shot more weddings then I care to remember but my last wedding was over 20 years ago.
Now it would seem that I may be in need of a wedding photographer in 12 -18 months so I thought I would have a quick google to see what's the current trend.
I'm not going to comment on the cost, usually you get what you pay for, but one thing that strikes me is how most photographers that I've seen have different packages based on the number of hours they work. I find this strange as in my day your job finished when the reception finished for which you charged a certain amount and then the cost of the photos would be on top of that, depending on the number you purchased.
It seems that nowadays you can pick a package that starts at the bride's house and finishes anywhere during the day, from the end of the church or after the speeches or anywhere in between.
I would like to hear from any current wedding photographers in this forum, How do you charge?
