For a while now, I’ve been on a quest to find a free alternative to Spanning Sync; that is, an application that offers bi-directional Google Calendar and iCal syncing as good as or better than Spanning Sync, all for the grand price of nothing. So far, I’ve found four apps, the latest being Plaxo, which I’ve been content with since I first reviewed it. Now though, there seems to be a new contender — BusySync 2.0.
Announced at Macworld, BusySync 2.0 is the upcoming version of the BusySync app, a preference pane that syncs iCal calendars over a local network or the Internet without the need for a dedicated server. While this is a great program already, version 2.0 makes it even better by adding bi-directional Google Calendar-iCal syncing. Unfortunately, BusySync 2.0 still doesn’t fulfill my “search for a free Spanning Sync” criteria, as it is simply not free. BusySync 2.0 will cost $25 when it’s released in February (but if you get BusySync 1.5 for $20 now, you get a free upgrade to 2.0 when it comes out), though the upcoming public beta will let you try it out for free. Still, this is a lot cheaper than the $25-a-year or $65-one-time price for Spanning Sync.
While it may not be free, BusySync 2.0 may turn out to be a good, cheaper alternative to Spanning Sync when it comes out. But until then, there’s still plenty more options.

I've been very pleased with Plaxo. I sync Google Calendar, iCal, and my phone with it. Only problem I've had is that Yahoo! has broken functionality with it.
I work for CallWave and we just launched a cool new visual voicemail app made just for Macs running Tiger or Leopard. Here's a podcast if you're interested in seeing a demo: QuickTime: http://www.callwaveblog.com/podcast/callwave_apple_voicemail_app.mov
After a little googling, it looks like GCALDaemon, one of the alternatives mentioned in the post above, isn't really Leopard/iCal 3 compatible. So, until it is updated, it is a non-option.
Just a word to the wise.
