I have a really cheap setup. I use a Dev Tec drum processor that I bought in the 80's for about $50. It has a motor but I often just turn the drum by hand. It has a water bath; years ago I drilled a hole and inserted a fish tank heater through the side; it's pretty rock solid at about 98 degrees F, and I get excellent and repeatable results.
I mix my own developer, use diluted vinegar as the stop bath, and use Kodak Blix.
