Hi Mary Jo,

A few years ago I was looking at globes for an exhibit to display  
where you would arrive if you dug a hole directly through the center  
of the earth and came out the other side -- the question Alice asks  
herself as she is falling down the rabbit hole.  We eventually built a  
contraption with two tiny video cameras pointed at the antipodes of a  
motorized globe that visitors could control with two knobs.  It didn't  
seem to me that any of the globes I could find were tough enough for  
direct manipulation by "public hands" (nice description!).  The one  
candidate we considered was a Cram 12" diameter with a "Horizontal  
Ring Mount" meant for classroom use.  This mount is a simple "cradle"  
device, much studier than the usual gimbals -- but it might be a  
problem that the globe can be simply removed and rolled across the  
floor!    It seems they no longer make that style, but a few dealers  
seem to have them in stock (though they may be out of date  
geopolitically) :

One of my favorite globes though is not a globe at all:
