Guy Recommends:  SolarWinds' Free Bulk Import Tool

Import users from a spreadsheet.  Just provide a list of the users with their fields in the top row, and save as .csv file.  Then launch this FREE utility and match your fields with AD's attributes, click and import the users.  Optionally, you can provide the name of the OU where the new accounts will be born.

There are also two bonus tools in the free download, and all 3 have been approved by Microsoft:

1. Bulk-import new users into Active Directory.
2. Seek and zap unwanted user accounts.
3. Find inactive computers.
