	I have dealt very successfully in the past with a company called

	MicroMetals
	1190 N. Hawk, Anaheim, CA 92807
	(714) 630-7420

	They even have a Mass. Rep:

	Anchor Engineering, Newton Upper Falls, (617) 964-6416
	(old number... may be (508), now.)

	They make cores of all types and materials, including toroids; they
also have "engineering kits" for about $50.00 which include dozens, if not
hundreds of cores, in dozens of values, and include very good design info.
They have kits for RF, Audio, Power, etc.

	They were also very reasonable to deal with on small orders.

[I am in now way affiliated with them; just a satisfied customer]
