I used my last batch of Rollie Digibase 4 chem kit a few months back and have been using the Tetenal 3 chemical Press kit. I'm fine with the results of the Tetenal chemistry. The grain seems just a bit more pronounced but for me the change is not that noticeable. Note, however, that all I do is scan. I don't print optically nor do I print (from a scan) over 11 x 14 inches typically.
I have a GE roaster that works well as a water bath but just bringing water to temp in a large pot will do fine for temperature control at 100F / 102F for the length of time it takes to develop one batch. You may need to adjust the temp again before a new batch though, I make the bath about 1F above the temp I need to compensate for ambient loses from the uncovered sides of the bottles / developing tank and loses from pouring. Nothing scientific to determine that, just a WAG and it seems to work. You can preheat your bottled mixed chemicals in a water bath of about 140F to 150F using a 2nd large pot on the stove. After getting the water to 150, put your room temp bottles in the pot so that water level covers about 2/3rds to 3/4ths of the side of the bottles and move them about every minute or so watching the temperature of the developer carefully. You want to pull the chems out before the indicated temp reached your target because it will most likely creep up a little before stabilizing. When you hit your target just place your bottles in the warm water bath and start your developing process. The warm water bath should hold it's temp stable enough to finish the developer and blix steps in the required time without issue.
My last few rolls of C-41 using the Tetenal kit are here. Note that several rolls are pushed 2 stops.
