The Heckler by Brian Tudor.
Loads of great visual stuff, great sleights. You can get it quite cheap at penguin magic.
Also the Dave Krenzo videos (coins & cards) are good. Very visual stuff.
The videos by Richard Sanders (the show vol 1, 2 & 3) are also good. Very visual effects (cards and coins)
David Acer's extreme close up DVD (GREAT visual magic, mainly cards)
Anything from Lennart Green will keep you going for life too...
That's already a good selection me thinks.
