You could also use Cloudflare, the SSL isn't registered to you specifically, but works fine and wildcard works as well, in addition it provides CDN and fast DNS, even the free plan has SSL now, we are on the pro account which is $20/mo for the first site then an extra $5 a month for each subsequent site (you can have as many subdomains as you like for the wildcard dns, they don't count as extra sites).
*edit*
The certificate is issues by Global Sign, and as you can see on
https://fanart.tv/ will say something like Issued to: ssl6975.cloudflare.com so if it's important that it says it's registered to your domain personally then it's no good, but if you just want wildcard ssl that works, then it's not going to get much cheaper than free.
