Ilfotec may be what is 'equivilent' but I find that in 'usage' ilfosol-S was closest (was able to dilute from concentrate), except I Think you have to use more chemistry on most of ilford stuff than the concentrated HC-110. (1:9 vs 1:31 or even 1:119).

Also if I am not mistaken Kodak doesnt even make their own chemistry anymore, but rather this one specialty chemistry group operating a factory that Kodak once owned and just putting out product with kodak's name on it. So by boycotting you are not hurting kodak at all but rather a chemical company making both their own and some for kodak.
