Another view: SSL-Tools. Do not expect help from CAs, because they do not like cross certs but their own root as anchor. I buy just such certificates which chain to an anchor in the third row. For DV, I go for RapidSSL Standard, which resolves to DigiCert Global and CyberTrust. For EV, I add ECDSA via Comodo which resolves to AddTrust External.
