What's a good program for syncing files between computers? I've been using Synk from Decimus off and on for a few years to sync files between two Macs.

Since upgrading to Lion, Sync 6 has started hanging during the process of scanning before the sync. Upgrading to version 7 is $45 which seems like a lot. 

Is there another program out there that does the same thing? I don't need it to sync the contents of files that have been changed on both computers, just copy the most recent version of a file (or a new file) from one to the other. I'd also like to be able to have it ignore files with a specific Finder label.
If you can use command-line tools, try rsync.

For the label part, see Rsync filter: &quot;OS X label&quot;.
