This widget needs the ability to weed out old price entries. Most of the entries I'm seeing have prices way too low. $1.98 gas? Nope -- that's from an entry at least a week old, and this in a period where prices rose by 15 cents.

I think this is a very neat concept and could be very useful...but only if the information in it is timely, and only if the old prices can be screened out like at the GasBuddy sites.
