I have used ID Guard for years now. I typically cancel my subscription intermittently, as I don't need the service except around the end of fiscal quarters. 14-16 dollars to be able to check your credit scores/history/public info is a good deal considering all the crap you used to have to go through just to get your score. They also have some cool services that help you calculate your new scores if you increase/decrease specific bills and debts etc.

If you are planning on using ID Guard, I may be able to refer you and get us both a discount.
