Where do you get a replacement shaft? I can't find any online

You don't need to pry the bottom plate off and risk damaging the seal. Simply apply firm pressure on the shaft against a table while simultaneously wiggling the bottom plate back and forth with a large flathead screwdriver inserted into the charging hole on the bottom. It will pop off smoothly leaving the seal untouched and not scratching the housing or charging plug.

Like the previous comments I also am looking for the replacement shaft. If anyone has found a source please leave a comment with regards to where they can be found.

Thanks for the help

Like everyone above, I can't locate the "replacement shaft". Anyone have any ideas who might have one? A $179 toothbrush should last more than the one year warranty! Is the Braun Oral-B any better?
