sync certain folders of two macs

Hi

I've ordered a refurb macbook pro to arrive in a few days. I have a mac pro at the office, so the MBP will act as a home working solution at evening and weekends.

As a wishlist I would really like to be able to sync the following between the two macs every evening and morning;

• documents folder
• sites folder
• a htdocs folder
• mail (this one may be tricky?)

As my files can be quite large sometimes (psd's etc.) I can't really go down the dropbox route as the office internet has slow upload.

Can anyone suggest any programs (paid) to be able to acheive this?

Both machines will be running Lion.

Thanks

Wayne
