No predatory pricing (StartSSL has $25 revocations), free (AlphaSSL) and user-friendly (StartSSL is a UX nightmare). PositiveSSL is probably the cheapest, well supported cert (certs can be had for $3-4/y).
I've bought from the below, there are other resellers around the same price (Namecheap being one). IIRC, they routinely have 20+% codes which get you to $4/y.
