Go to Dashatou second hand market and buy projector and their spare bulbs.
There is currently a shortage of projectors and their spares in Kenya.
The few available are for a bomb.
If literally want to go for mass market the go to a town known as Yu and load hawkers items.
I don't want to reach the end of my life and find I just lived the length of it.
I want to find I have lived it's breadth as well.
