Yes, Gay Video Data Base is very good. All Japanese performers, listed with different names for different companies. There is a good search feature for names of videos, performers and companies. But the guy that runs it is very strict about no personal info on players as well as any suggestion about illegal downloading. They also list their personal channels like OF. It seems to be very complete and accurate. You can ask questions that he will usually answer as well, in English. The titles are mostly in English but a lot of the discussions are in Japanese. My only problem is there is usually just one photo so it's sometimes hard to identify a performer if you aren't sure of his name. I use it all the time.
