I use StartSLL and have found there support excellent.
I have not yet gone through validation for the wildcard SSL, but it looks fairly straight
forward.

StartSSL are great for regular domains (though I've not used any of their paid
services yet), but they refuse to support single character domains such as
"p.im" - according to their support team it because of fears of misuse of the
domain. I'm unconvinced by this argument, I think they were just fobbing me off.
