Many of our customers realize that fact, but are nonetheless extremely happy to use SSLMate. We're not a normal certificate vendor, and the ease and automation of SSLMate sets us far apart. If these features aren't important to you, Namecheap is a fine choice - I used them myself before creating SSLMate.
I understand, but during times when you can buy a decent whole web servers for just $60 per year with traffic and all, the SSL certificate prices are just outrageously high!
