Nextrend is currently offering real time e-mini quotes free for six months. I use it and it's pretty good. Not a great charting package but it works for intraday.
This is a CME offer, not specific to Nextrend. If you are already paying for a data feed/charting package from any of the major data vendors, then you should be able to request real time data from CME free of charge.
