Synchronise folders on 2 PCs?

[ajf]

I have 2 Windows 7 PCs - a desktop and laptop.
What is the quickest easiest way to keep some folders synchronised?
It will usually be desktop to laptop rather than both ways.

Thanks everyone.
I will have a look at the options.
The total folder size is 150Gb so might leave the Live Sync if it syncs across internet!
Synctoy, just downloaded, looks like it will do the job but will check out the others too.
