I own this set of dvds and they are among my most prized possessions. The effect you're refering to is called the "Laser Deal" (or "Snap Deal", same thing minus the laser pointer) Lennart teaches his entire lifes work on this Master File set, it's worth every penny of $160. When I bought this set I didn't leave the house for a week!
There is also another 6-DVD set of Lennart Green's card magic available through Meir Yedid's website called "Lennart Green the Classic Collection". This set was produced a few years before the Master File set. They both teach about the same material. I'm a Lennart-o-phile so I just had to buy both sets. They are so good you almost want to send the guy some more money. Here's a link to Meir Yedid's site and that set:http://www.mymagic.com/green.htm
Note: Penguin has these listed as out-of-stock, so I published the link to Meir Yedid's site and ad for the set.
The thing I like about the Classic 6-DVD set is that volume 1 is his very first DVD he did back in 1995 or 96 (transfered from VHS). This was the tape that introduced me to Lennart and really got me interested in his work. If this were the only DVD I ever had of this guy it contains enough original material to keep me busy for twenty years. Volume 1 is almost entirely moves, sleights and ideas of a highly original nature.
SO, first off I wouldn't hesitate about buying the Lennart Green Master File, that's a no brainer. Then, if you decide you're really into this guy's work spend the $110 and buy the additional Classic 6-DVD set from Meir Yedid.
To be honest, I prefer the 6 volume Classic set over the Master File. I have no idea why as the Master File set is far superior production wise. Nevertheless I'm so glad I bought both sets. Much like a college education, I look at these sets as an investment in my education.
ALSO, there is a brand new 2-DVD set called L&D Lennart & Dani. It contains all of Lennart's latest work since the Master File series. It's the best set of DVDs I've bought in the last five years. Lennart's cull technique is worth five times the price of the set alone. This Dani DaOrtiz is another new kid on the block with some unbelievable material-- I'm buying his $160 Master File set next. Here's a link to this new L&D set:http://www.penguinmagic.com/p/S15416
If, by chance you can't afford the DVD sets right now you can buy Lennart's $10 booklet called the "Snap Deal", which is basically the exact same thing as the Laser Deal. Penguin has it listed as out-of-stock, but if you hunt around you'll find a copy (Mr. Green is from Sweden so his written english isn't that great-- BTW, he is a retired doctor). Here's a link to the Snap Deal booklet:http://www.penguinmagic.com/p/386
If you have ANY questions about Lennart Green or any of his DVD sets feel free to PM me. I've been his biggest fan and hard-core student since 1996 and have (I'm embarassed to admit) two sets of every DVD he has ever put out.
I almost forgot to mention another of his DVDs called "Green Lite". This DVD contains a set of self-working tricks he invented. Another must-have for your collection.
Run "Lennart Green" through Penguin's search engine and you'll come up with a list of everything he puts out.
Also, there's a LOT of performance material on Youtube of Lennart performing his magic. I find it absolutely mesmerizing.
