The mainline distributors (Allied, Newark, Mouser, etc.)  have excellent
selection of Fair-Rite and other cores. Admittedly to a neophyte the
equivalence of Fair-Rite or Laird part numbers to an Amidon-style number
may not be evident.

Clifton labs has excellent webpages of examples and is also a good way to
find the cores sizes and materials commonly stocked at the mainline
distributors using the manufacturer's part number (often with cross-ref to
Amidon style number as a strong hint!)

Recently some here expressed concern that the mini-circuits part may
saturate with medium DC currents. Of course if you are doing a SMT
production run you don't want to use bigger cores than necessary and most
of the mini-circuits parts tend to be physically very tiny to meet this
market. But if you wind your own on bigger cores this is a non-issue.
