I just replaced my bearings. Took it to my LBS to remove the old ones and found the replacement 6003 17x35x10 sealed bearings at a local industrial supplier for $10 each--you can find them for $5 or so online but by the time you pay shipping and wait for delivery it's about a wash--cleaned up the spindle on a wire wheel and spend 70 cents for a couple of new circlips. The guys at my LBS installed the new bearings with their headset press and didn't charge me anything at all for the removal and install. Now if I could only get the frozen Death Fork out of the head tube...
