Sorry if this sounds stupid, but what's the difference between the GEOTRUST and ChainedSSL certificates? ev1servers have geotrust for $49 and chainedssl for $19.95, for the price difference, what does geotrust offer that chainedssl cannot?

With the ChainedSSL you need to install two certificate, one of which is the intermediary. With Geotrust, you only install one. The thing is really the server and browser compatibility. I rather use the geotrust quickssl and have no problems with that.
