It has been a while since I checked out this thread, but it looks like Fog has actually improved their service to just plain old bad from absolutely horrible. At least they are sending to some of the folks up-thread. Even if it takes days, but that might be better in some ways (delay helps obscure BTC transfers).
Still, I would think bitmixer.io's TOR service should be better, but I have only used their service "in the clear".
