The Engl SE has been discontinued. There are still a few dealers with a few units left in stock however. I used to own a FB100 and it was a cool amp. You might also want to check out the new Savage 120 MK2. Should be released in a few months.
If Herberts been on your mind for that long, just go for it man
I feel that if your mind's set on something, it's best to get that and not look back.
But, there are some great amps mentioned already.
I've had three Diezels, VH4, Herbert and then Hagen.
I miss the VH4 and Herbert, but since the PRS Archon I finally found that epic tone that really ticks all the boxes.
