Sure are, and to build one of the Solid State coils you're looking at close to $1000 for a small 1KW sized one. multiply by 4 for those larger ones at least. You need some serious equipment for the professional SSTCs. Also in order to use a computer for input like midi, those large coils need to use SPDIF optical lines due to the massive EMF fields they produce.
Classic TC's like the one shown here are still just as impressive, just that they can't play Supermario Brothers or a StarWArs theme...
$1000?? What the hell, are you using gold plated mosfets or something?
I know that you can build a decent sized SSTC for a lot cheaper than that. The parts aren't THAT expensive, and you also get a plus of smaller size (less magnet wire to wind, therefore less expensive) and no tank cap for the primary side so that wipes a good chunk of change out too.
Just use a PLL controller, and you can play actual music music too, like how Fiddy's plasma speaker works.
Or, you may be referring to a DRSSTC (dual resonant solid state telsa coil)
Those are beasts. It's basically a SSTC with a primary capacitor. You actually have to interrupt the half bridge in it otherwise it would destroy itself from overcurrent and overvoltage due to resonant rise.
The arcs on these are insane. They're also expensive, and yes, would cost a good chunk of change for one... you have to use massive mosfet or IGBT bricks and heatsinks for these. You also need a nice bank of capacitors for the primary. And I mean a NICE tank. Otherwise they go boom boom.
