To the nub of your question:
A good, accurate table saw is the workhorse of most shops.
While a SCMS is very handy, a good TS is much more so.
As Doug mentioned, a speed square and a circular saw works well for cross cutting wider stock. It's fast and accurate. I might add, a good, sharp blade vastly increases the enjoyment of the experience.
