Here's the TUAW
link from late September that clued me to this problem and has allowed me to wait until 10.6.2 comes out to see if that helps before buying a replacement battery.
With this being a first gen MBP, I might decide to buy a newer, refurb model before spending around $100+ for a new battery since I would not mind having a faster processor and a larger HD and being able to have more than 2GB of RAM.
YMMV
