coin magic

I've been trying a couple of things like retention vanish and french drop but they seem really obvious when standing right next to someone. One girl I got a great reaction the first time I did the former but it has been met with eye rolling and another person immediately grabbing my other hand...

Where can I get the best Okito box?

I bought a magnetic ring the other day, and I was wondering if there were any other tricks with it I can do (besides penetration tricks and disappearing coin). Does anyone know any? Also, does anyone know how to make a magnetic coin disappear without such a loud clinking noise?
