I can throw in 2-cents in on developing your own color. It is not too hard. Much the same as BW except the temperature and the shelf life that sucks. You can get something like the Jobo or Unicolor C-41 press kit from
freestyle.biz. It contains all you need. You can process it with a tank like your BW if you do it that way.
I put one of those small coolers in my sink and put hot water from the faucet in it. I place the pre-soak water, Developer and Blix in it with an accurate color thermometer to get it to 102°F (39°C). I remove the chemicals from the cooler and mix cold water in to get it to 102°F (39°C) also. I place the chemicals back in.
Then process per the instructions that come with the kit. When you get near the wash stage, turn on the faucet mixing cold with hot into a container with the thermometer adjusting the amount of each until it reads between 95°F (35°C) and 105°F (40.5°C). Leave the adjusted faucet running. When you're ready to wash just fill the tank, agitate several times, pour it out, fill again, agitate, etc for 3 minutes. Add the stabilizer at room temperature and your done ready to dry.
Doing color at home is best when you shoot a lot of it. My problem is I only do color now and then you waste your chemicals due to the short life after mixing. And the darn instructions won't go out on a limb and tell you just how many rolls you can safely process in a one liter kit. Some say 10 or so rolls or more if you rinse between developer and blix but I have never done that many within about a 2-month period where I'm too chicken to use the chemicals after that again and mix a new batch.
And, of course, my procedure comes with a disclaimer: your milage may vary ;-)
