Post From: SPX Cash Index Feed

Is there any way to get an accurate real-time feed of the SPX cash index? I've built a system through the spreadsheet study to calculate the differential between ES and SPX which I then use in a myriad number of ways such as plotting specific SPX prices on the ES. Unfortunately the SPX feed accessed by the symbol "SPX500" is inaccurate as it is off by roughly 4.5 points at the moment. If the difference between the symbol 'SPX500' and the SPX cash index is static I could put it into the calculation and account for it?

Also, the symbol NQUS500LC-NQGI has totally different prices which renders it unusable for this purpose.
