Where is a good place to listen to good opera on the internet?

I’m on an opera kick at the moment, but I don’t have any of my cds of recordings around; where can I listen to it on the internet? I mostly like Italian and French opera; some of my favorites are Carmen, Turandot, Tosca, Gianni Schicchi, Nozze di Figaro, I Puritani, Magic Flute… ones along those lines. Youtube hasn’t been really helpful, and I’m wary of most of the online radio stations because they’re generally geared toward more popular music. Has anyone found one that has a good selection of classical opera (I really don’t like anything too new; I especially hate opera in English!)?
