"Instead, I would like to know what is your recommendation for an easy to use, safe and practical way to encrypt my email communication that I can set up right now?"

None. Although, thinking about it right now, it might be possible to develop a simple Chrome extension/userscript to provide easy encryption/decryption for clients using PGB or some other method. One could have it plug straight into gmail (or any other client) and decrypt on demand / encrypt.
