If people post replies I'll update the OP with information on various credit monitoring services including how much they cost, services offered, and accuracy of information.
Pros:
Free once a year. Report is viewable for 30 days and users can request mailed copies. Straightforward layout allows you to readily browse information. Step by step process leads you through each of the 3 credit bureaus. Very simple online dispute process.
Cons:
$15 to view all 3 of your credit scores. Because viewing your scores does not require a purchase the verification process can be tedious. Be ready to answer specific questions on accounts, address and other personal history for as far back as 10 years. Limited follow-up after 30 day period expires.
