high current DIY inductors
NiHaoMike:
Found these inductors for really cheap:

They're only 50A (I can lower the output current rating to that) and very heavily discounted for some reason. (Anything to beware of? I haven't tried ordering so it's possible the shipping fees would make it not as much of a bargain as it appears.) Would these be suitable for my application or would they be too lossy at the frequencies I'm working at?

These are strictly for 50/60Hz choke input filter applications; losses will become prohibitively high around 400-1000Hz, depending on the lamination thickness and grade of electrical steel used.
EDIT - but that's a helluva deal so I ordered one.
NiHaoMike:
What source would you recommend for getting a few of the Kool Mu cores? Searching Digikey or Mouser doesn't give any results for cores, just (small) complete inductors.

I think Amidon http://www.amidoncorp.com/ used to show stock of items other than their main catalog (which BTW is Micrometals powdered iron, most of Fair-Rite's catalog, and Magnetics ferrite toroids). Probably you can still RFQ, but no telling stock...
https://elnamagnetics.com/ used to have online inventory checking but seems they dropped it.
https://lodestonepacific.com/ has inventory checking but it's kinda broken?.. old fashioned RFQ and purchasing.

I've gotten samples from Mag Inc. and MMG Canada Limited. Würth offers inductors and custom magnetics.
