Found this today while googling for Snap-on Ferrite chokes, no prices, but some good info if you click and scroll around. Made me wonder, how do I become a EMI/RFI chasing tech? The problem is not new, but seems to be on the rise lately..I certainly have been affected by it!
http://www.leadertechinc.com/product...FURlfgodoHMASA If you go to "Catalogs" tab, then "Ferrishield Ferrites" for example, found out there are different ones for filtering different types/frequencies of EMI, Plus I think there are some"General use" ones also. Makes me feel Lucky that the random ones I bought from different sources actually helped my problem!
