I just wind my own E&I trannies.
It does mean I have to buy at least 50Kg of core material at
a time, but the GOSS I get is extremely good low loss material,
and has losses almost identical to good toroidals.
At 0.8 Tesla, the iron U is 17,000.

Measured up to 25,000 at this induction value and around 6000 at 1.4T !

Glory day for Lance today !

Plitron make good toroidals. No need to wind one's own if you really want
a
toroid.
