We buy our certificates from Bulkregister, $12.95/yr for single host (GeoTrust RapidSSL) and $89/yr for wildcard (Comodo Essential Wildcard). We paid for the maximum possible duration (4 and 5 years) and do not worry too much about renewals, we can always switch after that time if we see a better offer... StartSSL is free but limited to 1 year validity and too much paperwork/legalese for my taste.
