How big do rattlesnakes get?

What is the biggest species of rattlesnake? Exactly how big (length and weight) do they get? I know that the longest venomous snake is the king cobra (about 18 feet, I think!), but I have a vague recollection that some rattlesnakes, while much shorter, actually weighed more. Is that right? Any information would be appreciated!

The Eastern Diamondback rattlesnake is the largest species of rattlesnake. Reports of specimens over 8 feet long have been reported but they commonly top out at 7 feet long.

Here's some fairly current info from The Desert Sun:

Rattlesnakes are wide in proportion to their length and therefore relatively heavy. The heaviest rattlesnake ever captured was a western diamondback rattlesnake (known to herpetologists as Crotalus atrox) that weighed 24 pounds and was 7 feet, 5 inches in length.

A 4- to 5-foot rattlesnake typically weighs about 8 pounds.
