Not really. A TO220 SCR and a 6mm*10mm*16mm ferrite toroid with 10 turns 
on it. Not a lot of effort to get the dream coil.
Having identical PCB`s is also nice.
Ok, there is a pulse driver and a remote too.

It may all seem complicated, but to me, it has been a way to build 
something that is "my own" and possible. I still am not able to design 
my own DRSSTC, although I am getting there.

It can do both things!. Set the BPS and vary the voltage with a variac 
(3 phase, of course) or set the voltage (for constant bang size) and 
vary the BPS.
The triggered SISG is designed to deliver the best of all worlds, and I 
still don`t understand why I seem to be the only listmember that has one.
