Good free ones:
A free heads up display (http://www.holdemranger.com/realtime.html)
Free results tracking software (http://www.checkyourbets.com)
These are certainly good enough until you reach 25$ No Limit and above, and could probably suffice for your whole poker career. Paying for hold'em manager or poker tracker does have some nice benefits, but I don't think you'll see their usefulness until you reach 25$ NL at minimum.
