Any of u own one of these?
For those that do not know the effect, its a signed bill appearing in a locked brass tube.

I am looking for a good quality one. Any to recommend?

Viking has a good one but the price is on the high side. The Magia De Bazar also has a similar version which is cheaper.

But then again, I don't seemuch use for it.

i think such can be a good ending for a routine?

i like "to impossible locations" ending, but i would do it by itself. i suppose bill in lemon will provide a more amazing ending for a bill routine. if i do a ring routine (say ring and rope, ribben and rubberband), i may end off with a vanish and appear in a ring box for example? or coin tricks will be nest of boxes? anyway, if u like it, just get it. can be quite troublesome though, and not easily resettable.
