Personal email cert for S/MIME

I need to start signing some email I send, so I figured I'd use Mozilla 
Thunderbird's built-in S/MIME functionality. That requires that I import 
a PKCS#12 certificate.

However, I only see two "major" free email certificate options: Thawte 
and Thawte does not seem to offer any means to generate a 
standard PKCS#12 file (their web site only wants to install certificates 
directly into the application, which Thunderbird can't do). 
does offer PKCS#12, but their root certificate will not be my 
recipient's trusted root list, and I'd rather not deal with that hassle.

Anyone have any advice?
