I've never been too fond of Earl Grey tea. Something about bergamot just rubs me the wrong way. But we all like what we like and if you happen to like Earl Grey you might want to check out a nifty site I ran across today - Tending Toward Tea.
It features a rather staggering list of Earl Grey varieties (who knew?). I didn't click every link but it appears that most of them have been reviewed. Pretty impressive.
