I've never developed C41 myself before, but I do a lot of b/w and also print b/w and RA-4. I'm looking at two Tetenal kits, and I'm not sure if there are any drawbacks or quality differences between them, or compared to other brands. The links are below. http://www.bhphotovideo.com/c/product/109269-REG/Tetenal_T102228_C_41_Kit_for_Color.html http://www.bhphotovideo.com/c/product/109267-REG/Tetenal_T109306_C_41_Press_Kit_for.html In general, what chemistry will provide the best results? I'll probably test a few films, but I will likely be using Fuji 800z, 400H, and possibly the consumer versions (once I test them). I plan to rig a temp bath with an aquarium heater. I'm looking to get the cost down to $1 - $2 per roll, so these kits are attractive, but I don't want to sacrifice image quality. Thanks for any help.
