Active Directory - limit to OU depth?

Is there a maximum recommended OU depth for Active Directory?  I was told once that 5 should be your maximum OU depth.  Is this true?  Seems kind of limiting.

    There is no physical limit, but Microsft recommends you limit to 10 according to the article below.  This is just good design which is critical to allowing for the easy and managable administration of AD.

    In this case, less is better :)

    Designing a good AD structure is very important and needs to make logical sense for your organization.  If you have an OU that is 20 levels is going to be EXTREMELY confusing to manage and to make any sense of policies and other admin. tasks. The important thing is for it to make sense and be easy to understand so just make sure you plan it out very well.

    Thanks a lot, that article was very helpful.  I realize that less is more, but there are just a couple instances where I may need to go 6 or 7 OUs deep and 5 seemed a bit extreme.
