David Roth has a great DVd on the Shell coin and it's uses.
It is very well taught and David has a great way to impart his knowledge.
Chris Korn also has some great material on the shell coin routines he does. and many of those routines are based on the work of Troy Hoosier.
Troy's DVD's will teach you how to handle the shell ina naturla mannor and in a less traditional mannor than David's DVD's do.
I saw the coinman walking DVd and thought the routines were ok but I have yet to do any of them for an audience. I can't explain why exactly but Chris Korn and Troy's material is more my style i guess.
Perhaps one of the best DVD's for showing an awesome use of the shell is Coinone by Homer Liwag. His handling is very very natural as well and the routine really get's gasps.
About the shells themselves: I have Johnson shells, Schoolcraft shells and Lassen shells. I use the Johonson Morgan and Eisenhower dollar shells and they have served me well in the last 12-15 years or so. The schoolcraft shell sounds a bit tinn like but when used properly it works great. The lassen shell is good I tend not to use it as much though.
My advice is to order a shell your going to learn with and then get a top of the line one so that if you bend, drop or otherwise mutilate it, you won't feel as bad.
The Lassen and Johnson shells have the least distortion of the face of the shell. It is so good that I forget which one is the shell if I leave it on my close-up practice table.
