I agree. PK silverware is def. the best starting point, then PSI 4. Banachek really is the master when it comes to metal bending. You not only learn the how to's, but the psychological subtelties behind it all. The tine bend you saw probably comes out of PK Silverware
I've just finished watching Patrick Kuffs Metal Bending dvd and it's also really good - it's sort of an encyclopedia of metal bending. I'd really recommend getting it after Banachek's stuff. I know that a couple of people complained because Patrick Kuffs didn't give enough credit to the various people who invented the bends - but I know he's apologized for that etc. Kuff's deals more with the technique of bending the metal than the psychology of it, but there is a great amount of info and some nice ideas on this dvd/video. He also has a nice revelation for the tine bend.
Richard Osterland has a really nice spoon bend on Mind Mysteries 3, but I wouldn't buy it just for the spoon bend (but the whole series is excellent stuff).
Guy Bavli also has some good spoon/key/nail bending stuff. I personally don't like his style that much and i haven't made my way through all of the material yet, so I can't really comment.
Morgan Strebler has just put out 'Liquid Metal'. I think this may be the 'super dooper' stuff you were talking about. I've been meaning to give it a review, but haven't had the time to do it properly. There was a ton of hype (true penguin style

) about this dvd, but it is really just his version of Banachek's pk silverware routine. It has one or two nice handlings, but nothing you won't find on Banachek and Kuff's material, so I wouldn't waste my money (well, actually I did - but I meant that you shouldn't waste yours.. I'm sure you know what I mean).
Sean Fields has some good stuff in 'Explicit Content' - but that's been discussed and reviewd at length on the forum.
I've also just ordered Metalogic - a spoon bends, then breaks and then is restored - I'll give it a review when it arrives (when i finally get the time)
