Thanks to AVweb for pointing out Skyvector.com, an incredibly useful site which has on-line versions of all the sectionals within the lower 48. Skyvector.com gets three thumbs-up from me!
AVweb also found RunwayFinder which mashes the sectionals with Google Maps. It is an interesting implementation but I find the Google Maps icons distracting since they appear on top of the sectional.
Both Skyvector.com and RunwayFinder let you click on the airport to see the FAA information on runway length, etc.
