While shopping for a basic SSL cert for my blog, I found that many of the more well known Certificat Authorities have an entry-level certificate (with less stringent validation of the purchaser's identity) for approximately $120 and up. But then I found that Network Solutions offers one of these lower-end certs for $29.99 (12 hours ago it was $12.95) (4-year contract).
Is there any technical security reason that I should be aware of that could make me regret buying the lowest end certificate? They all promise things like 99% browser recognition, etc. I'm not asking this question on SE for comparison of things like the CA's quality of support (or lack thereof) or anything like that. I want to know if there is any cryptographic or PKI reason so avoid a cert which costs so little. It, like others, says that it offers "up to 256 bit encryption". Thanks.
