We got our N2 at Airgas in San Francisco where we are located. You need to have a proper transfer container, a Dewar flask is most appropriate, otherwise they won't sell to you.
It is dangerous because it freezes tissue pretty much immediately. Your eyes are mostly water, so shielding them is incredibly important. As for skin, you can get small burns if the N2 lands on the skin and sits there, or if it gets into your clothes, which can keep the freezing liquid close to your skin leading to worse burns. Interestingly, small amounts of N2 on flat skin, say the back of your hand or arm, will boil/evaporate off before burning you. It's just a good idea not to play with it (i.e. use safety precautions) and tempt an injury.
It is not toxic, as grhowes said. So, eat your fill of the ice cream!
I have to admit that during filming I got a little carried away with the torch. You can adjust it to a smaller flame, or even hold it further away from the brulee. These kinds of bigger torches are primarily used in restaurant kitchens to deal with the large number of orders that come in all at once.
It still tasted good even though it was a little burned. :)
As with anything, the quality of a product is usually defined by how much it costs. Thanks for going shopping. Was any one brand more reliable than others?

Marshmallow fluff is used in less traditional recipes, but I don't think those can really be called true fudge.Food Science - Liquid Nitrogen Ice Cream
