"Great - no problems in 7 years"
It simply works with no hassles. Set it and forget it. In 7 years I haven't seen the first problem with it in any version of Windows from XP to Vista to 7.
Not the cheapest, but you can find it on sale for next to nothing.
I don't think you can beat it. It simply works manually or automatically time after time with no problems or hassles.
