Comment on BusyCal

Far too expensive. Especially for a per-computer license. It means for my wife and I to use it, I'd have to buy three licenses - 1 for the desktop, 1 for my laptop, and 1 for hers. I like it otherwise, and the syncing options are nice, but realistically it doesn't offer enough over iCal for most people and especially not enough "Pro" options like seeing other people's schedules or other Outlook functionality which is really the standard.
