I admire all 7 of his feature films (though i agree with Tarkovsky himself; he was less pleased with Solaris).

You may be interested in Senses of Cinema internet magazine, which has a fine article on him, and to see that Mirror in particular is doing very well in a poll of top 10's there. It was voted the favourite film of Russian critics in a 1995 poll, i think- a big change from when it came out and had a lot of criticism for being too obscure for the public.

Eisenstein is another great director who seems a bit out of favour at the moment, for some reason, but i'm still a big admirer. We screened Battleship Potemkin at our film society, with specially composed musical accompaniment, and it was a success, of course.

Oh, and Man with a Movie Camera (Vertov) is a brilliant film.

Another less well known silent director is Yevgeni Bauer. He was overlooked after the 1917 Revolution but has been rediscovered. Have you seen anything by him? It would be a great shame if even in Russia your magnificent cinema tradition is overpowered by Hollywood. For instance, i wonder if the shower scene in Psycho would have existed (at least with the famous editing) if it hadn't been for Eisenstein and the Russian montage pioneers.
