I have also purchased a genuine battery from dealextreme for $16. It is a completely legit battery, and functions EXACTLY as the original stock one does. http://www.dealextreme.com/details.dx/sku.32444 I recommend this battery to anyone and everyone, it is WELL worth it over the cheap ebay knock offs, and it is a STEAL compared to what nokia charges. Also, dr_frost, I highly recommend you test that battery NEXT, because it really is the best, and completely legit.
