Most of the resellers out there are reselling Comodo certificates. Comodo is probably the leader in terms of number of certificates issued and you can buy direct direct from them to save the middleman. They offer two classes of certificates but both are essentially the same. The difference is the amount of insurance Comodo provides you and the level of authentication you must go through to prove who you say you are.

You can check them both out at: http://www.instantssl.com/ (the lower end) http://www.enterprisessl.com/ (the higher end)

Comodo's default InstantSSL root is not present in many devices (Nokia Series 40 and Windows Mobile in particular, IIRC). If you file a support ticket they will issue you a certificate chained to a different root. But, that root certificate is going to expire relatively quickly, and it is hit-or-miss whether Comodo will charge you extra for it (since it effectively makes your cert. an EnterpriseSSL cert.).

Comodo is also on the verge of getting its trust taken away from them, due to negligent behavior that was widely reported a month or two ago. If any more negligent behavior is discovered (not unlikely), I think browser makers will be forced to remove Comodo's root, making all their certs worthless. (They are already worthless to me.)
