ON4UN is a smart guy, and I'm sure that his recommendations are solid, but 
he's buying European products that are hard to find in the US. I doubt 
very seriously that there are any ferrite products we NEED that Fair-Rite 
doesn't make, and they are VERY ham-friendly if you approach them with a 
PROFESSIONAL attitude and a quantity order. They also have a very good 
distribution network if you poke around for it, and they're listed on the 
website. Fair-Rite is a VERY good US company based in upstate NY. 

See Appendix 1 of my tutorial for a list of specific Fair-Rite products 
that make sense for a group purchase of parts suitable for common mode 
chokes. Two of those parts are specifically intended for your use. You'll 
also see two parts listed (a toroid and a "big clamp-on") that are 
suitable for wound chokes.
