StartSSL's EV certs are pretty darn reasonable.
Still waiting for a cert request they flagged "for check within 2-3 hours" two weeks ago…
I have no idea about StartSSL, but some cheaper EV providers Comodo immediately ask you to use a lawyer or CPA to write professional opinion letters.
This allows the CA to do less work according to the EV guidelines, but massively slows down the validation process and may incur additional fees unless you have an in-house legal team or CPA.
