P.S. I will also appreciate ideas about places to purchase ferrite in

You might try Amidon (

(
http://thewireman.com/baluns.html#901). I don't think I've bought
anything from Amidon since Bill Amidon sold it, but see their brand on
small quantities of cores at the local electronics shop. Press Jones,
the Wire Man, is great to do business with.
