Well, one place is Information Unlimited... I can't remember their address
at the moment, but you should be able to find their ads in quite a few
electronics magazines (Popular Science, Radio-Electronics, etc).  In addition
to plasma globes, they've also got a variety of interesting stuff including
magnetic and sonic devices and lasers..  

One other note I might make, is if you get the plans to their "solid state
tesla coil" you can buy one of those small light bulbs that look more or less
like a clear globe, connect the output of the coil to bulb and provided that
the bulb is filled with a gas and the output of the coil is great enough
you'll get the same plasma globe effect when you touch your hand to the glass.
I've done this and it seems to work well, the only problem is to find a bulb
of the right size for the output of the coil.. (the filament should be right
in the centre of the bulb, otherwise you'll get effects greater in one
direction than the other)   If you DO decide to go this route, coat the base
of the bulb (where the metal screw connection meets the glass) with epoxy or
RTV as the unit tends to produce a corona at that junction...
