Hi Steve,
Yes, I use the white Semikron SKM400GB124, they are extremely robust, ultra fast, and are easy to drive. The IGBT`s in the coil ran for 3 months 4 times per hour, 15 seconds each time, 8 hours a day at 360V 600 Amps last year. That`s 12 whole hours on pulsed mode.
I think that they are worth the price:-)
Didn`t you use the same bricks for something in the past?

Steve,
I didn`t buy them used, but from a guy in Denmark who had them in the original box for a fair price
I`m having some problems with the coil at the moment, the spark output is falling drastic and is now just around 2 meters. I think that I need a new and better cap that can take some more RMS current, as the one that I have now only can take around 100A. And a new bus cap made from some large RIFA caps that I`m looking at... Finn and I took a cap out of the mmc, and unrolled the film and isolation layer to see if the cap was dead, but it had almost no self healing spots.
One headache just takes on another, and this may take some while before I can finish it... And there is getting cold outside, so there will be no coiling for the months to come...
I`m also making a new MIDI interrupter with a friend of mine at the university, but more info on that later
