I have not used any of them however, plan to order either the Rollei kit or the Kodak kit from Photographers' Formulary. The reason is I don't think using Blix is as good (in those other kits) as the original Kodak method. Shipping cost ways in favor of Freestyle. I would of thought that you could find something local in Chicago but things are different now. Good Luck.
The Kodak kit from the Formulary is excellent, as well as the Rollei kit. A separate bleach/fix is generally preferred over a blix. In any case, it's also recommended to add a stabilizer on the end. I use PE's mix with formalin and photo-flo (there was a url link here which no longer exists). Found 37% formalin cheap from a pet store (it's used to treat fish parasites).

stabilizer isn't needed for new c41 films, only older c41 films which would be long expired by now, I have been mixing my own (formalin isn't healthy for you btw).
regarding which is kit better, do a search here, it's been discussed to death.
the formulary kit isn't that cost effective if you use it with the listed capacity. I use the rollei 50 roll kit in my jobo.
