Chris,
     You would have to give us a link to the site to know for sure, but the 
dead giveaway to a solid state transformer will be the case (it will be 
plastic, instead of metal).  Also check for it to say 20kHz or something 
like that, they don't always include this information however, but usually.  
You can indeed use high frequency power supplies for a Tesla coil however, 
but they must be rectified.  These guys built their own HV HF power supply, 
pretty cool!

Unless the transformers say DC out, than they are most likely high frequency 
AC (DC, unless it was pulsed, would cause ion migration in the glass of the 
tube (and make it weak), so it is not ideal for an NST, also, rectification 
would provide only half the peak to peak voltage as AC, also making it less 
than ideal, so I'm pretty sure, these NSTs are high frequency AC).  Good 
luck.
Scott Bogard.
