While building the shelves for my shed a couple things came to mind as to why I need two or three saw horses.
1) I don’t have a proper workshop, or even a workbench, so I’m having to stack some studs on the ground to lift my sheets off the ground as I rip them with my circular saw.
2) These shelves would take so much less time if I had these theoretical saw horses.
For a nonprofessional, get the plastic/pvc ones, which will fold up and hang in a small space. Also think of getting a hollow-core door from a Habitat resale store to use for a workbench. Also easy to store when you're not using it.
