Keep it simple you just need a pan and shallow trough to pan in .....
Go through what you've panned a few times until you get proficient at panning.
It's the basis of all future prospecting that you need to get right, practice makes perfect.
If you don't want to spend much: try a garden sieve to classify the material, (if you don't have one make up a wooden box and use some insect screen), a largish plastic tub to wash in, and a large saucepan lid as a pan.
