one i got off ebay does work after rectification. the output looks 
sinusoidal, but it is 20khz modulated on 60hz. there is no need for either 
a resistive or inductive ballast because its built in, like most nsts. i 
think they do the same low coupling thing, so it is inductivly limited, but 
at 20khz and rectification, it acts as though it were a resistivly limited 
60 hz transformer.

The switching supplies sold as neon tube drivers CANNOT, in my experience,
be used as TC supplies, even with the addition of rectification, smoothing
etc. The supplies I have seen do not provide a CW HV output, rather they
output spikes of HV (6-10kV) 2-4 times a second to strike the tube, and then
a CW output of 600-1000V to keep the tube lit. This means that after
rectification and smoothing you will get a 1-2kV output, which is pretty
marginal territory for any spark gap tesla coil.

The fact that you have to use a DC supply also means you either have to
accept a 50% power loss in a resistive HV side ballast, or use a charging
choke which will then make the supply as big and heavy, if not more so, as
an equivalent coil and core style neon supply.
