I've used the Tetenal 3-bath kit and have gotten pretty good results for normal processing and 1-stop push. If you push, I don't recommend reusing the chemistry. For normal processing, I typically reuse it once. Fuji films seem to exhaust the developer faster than Kodak, so you might be able to get three batches through the chemistry with Kodak film.
The 6-bath kits are said to give better results for bigger pushes, which I don't do that often.
