Default line filter

I am building a smps and would like to use a line filter. The problem is that all the designs i saw use cca 2x1mH common mode choke, which I cant seem to find anywhere. Where can I get such a high value?

Buy the toroid core and wire and wind it yourself. That's my thoughts. This is about diy after all.

Peace,

Dave
