Hi Zou. The actual MINIMUM kit needed to process black and white film is small. You'll need a tank, measuring cylinders, thermometer, timer, scissors and clips to hang the film. If you're being good, buy new and support Paterson. If you just want to experiment cheaply, ebay is full of top quality kit for PENNIES.
Use liquid concentrates to start with- easy to mix and cheap. Something like Ilfosol, or Acutol.
Also, a 36 exposure 35mm film is five feet long. For your first eperiments try 24 exp films- they're much more managable for size when you're inexperienced.
The only 'skill' part is loading the spiral. Sacrifice one (outdated?) roll and practice loading until you feel confident. This is the only part of the process which MUST be done in darkness. Since you have no darkroom, a changing bag is a good investment.Again, ebay is full of them just now.
