I wouldn't know what to recommend. I was taught to use the stuff by a grad student and thereafter supervised for a while whenever I was doing something "high risk" - disconnecting cryogenic lines, moving around tanks, etc. Since I was using safety equipment and using approved containers, I and my department felt a few minutes of training and a few weeks of supervision was enough. Besides, safety in universities is notoriously lax, perhaps on the (often mistaken) assumption that people who can get four-year engineering degrees have a lot of common sense.
Designing containers for cryogenic liquids and using these containers opens up a whole other category of risk, and doing so without significant education and/or experience is foolhardy.
I think ezlid's post is a good primer, but handling liquid nitrogen is one of those activities where you really need someone watching over you for a while to catch you before you make a mistake.
Alone, in one's garage, is not the place to learn about the dangers of liquid nitrogen. People who have that attitude are the same sort of people who get careless (or just stupid) and end up with gastric perforation or other medical horrors.
If I'm good for nothing else on this board, I hope I am at least able to dissuade a few people from doing something very dangerous.
