Easy, cheap, and good would be liquid concentrates. A print developer such as Ilford Multigrade, and film developer such as HC-110 or Ilford HC. For a fixer, a liquid concentrate such as Ilford Rapid Fixer or Kodafix Solution. (I prefer Ilford because it is non hardening.) Fixers can be used for film or paper, but make sure you follow the dilution and capacity instructions for each use, as they are different. Kodak or Ilford stop bath is cheap as dirt and lasts forever. I like to use Hypo Clear. It is the only powdered chemical I use. Ilford has a version called Washaid, but I don't know if it is a powder or a liquid concentrate. I always just use Kodak Hypo Clear, as it is the only clearing agent my local store carries. Then, Photo-Flo or Ilfotol will help with spots...and you need graduates and storage containers.
So, my shopping list:
1. Ilford
Ilfotec HC
Multigrade Developer
Ilfostop
Rapid Fixer
Washaid (may be a powder, but I am not sure)
Ilfotol
2. Kodak
Dektol (powder)
HC-110
Indicator Stop Bath
Kodafix solution
Hypo Clearing Agent (powder)
Photo Flo
Then, as many bottles, graduates, trays, etc. as you need.
It will be more expensive than you think!
