Would be nice if something like this was on the official site but my guess as to why it's not (besides the general mismanagement of the site creation...) is that by default it shows higher prices for plans than people would be eligible for (ex: no income based subsidies). That would make them "look bad" and they'd like to show lower overall costs.
Bug report too: When I entered a zip code the first two pages of the results show up blank. Clicking page 3 and onward show the data though. If there's only one page of data nothing shows up at all (no paging links either).
