Morningstar has the best I've found so far. Is there anything better? (examples below). Also, if there are any I could download to a spreadsheet, I'd be forever grateful.
Note that morningstar erases their data so to only keep it on the same trading day, but they mark changes in deltas, volatilities, etc. Chains would have to be better than Yahoo Finance's too.

Thanks for your help!
