Here's the GUI for rsync (Grsync)...Yes, the learning curve has a little more to it, but rsync is one of the most complete syncing tools around, and has quite a few advantages over others...
http://www.opbyte.it/grsync/I haven't had time to set it up or learn it yet, but I've looked thru a vast amount of sync tools, and rsync is the one I've chosen...With it, I'm pretty sure no matter what comes up or what I add to my system, rsync will cover it...
