I agree with the previous posts, the developer needs to reconsider their pricing. It does, however, do what it does well. The latest version (beta) syncs Google contacts which is a huge deal for me, so I'm happily using it for now... and it's working great (on Leopard even). I only paid for a year (and not the lifetime subscription) as I am hoping the developer will adjust their price or another similar product will come along that also syncs Google contacts.

There were serious problems with Spanning Sync and Leopard. These were supposed to be resolved by the Leopard 10.5.3 update. However, it still doesn't work for me -- I get continual conflicts when syncing. If you value the integrity of your calendars, steer clear of this -- it just isn't worth the risk.

Works like a charm. If there was not that price tag. I have been using the program for almost a year now and have to decide whether to continue the subscription, extend to lifelong membership or take a look at other products.

When the beta was over I said I would never pay (at least not that much) for a service like this, something Google will offer for free soon. Google hasn't yet launched anything. I've tried gSync and BusySync both with duplicate entries and lots of hassle. SpanningSync GETS THE JOB DONE. It's so easy even my grandma could use it, I love this app. Downside is still the price, I think it could be dropped with 5 bucks at least but hey, we all want to make money and the creators of SS deseves it!

Great future alternative is: http://www.busymac.com/busysync2.html

The google feature is coming in Feb. and the price is right.

Yea it seems like a good app but the price has completely turned me off.

Beware -- 1.1.3 can't be trusted on Leopard. For me, it caused a variety of missed syncs and duplicated events meaning I had to patch up my calendars by hand. I regret the $65 I spent. Not sure there's an alternative though -- it looks like gSync has similar issues and GCalDaemon doesn't work at all on Leopard.

I used the beta too, and thought it was cool. I don't use it enough for such a hefty price tag though!

The newer version of GCalDaemon is a million times easier to set up - it comes with a GUI that you can edit the config with. I use this without any problems - and of course it's free!

I was tempted to try gSync when I came across it, but why change something that works?

Very shiny and loved the beta, however when they announced the commercial version I was completely priced out of the market. Very handy, but not so essential that $65 makes sense.

Gsync on the other hand. . .

There is an open source gCal/iCal sync here : http://gcaldaemon.sourceforge.net/index.html

I have used it for several months without issue. Set up is a touch more involved though.
