Just an FYI, in the last month or so Quandl has added futures options data from OptionWorks and in the last couple of days they've added equity options data from Quantcha. Subscriptions are $100/mo if you go mo-to-mo or $75/mo if you sign up for a year. From what I've seen of the futures options data, the history goes back almost six years and I believe the equity options data goes back 13 years. Seems like a good price compared to some quotes I've received from ivolatility.com.
