RAS were once the must-have home shop tool. Dewalt built their business on this tool - and for many years that’s all that Dewalt made… We had a huge old Dewalt that came with the business - that we used for crosscutting 4x, 6x and 8x timbers. The Dewalt RAS that we had - and others too - had a massive column, sturdy ways and stayed in alignment. Many cheaper saws got sloppier and sloppier with each cut - probably ruining the reputation of the tool. The saw could also be dangerous to use (kickbacks) for ripping and reported injuries were an issue for the saw.
Sears promoted the heck out of theirs - bearing the Craftsman brand - as the all purpose woodworking tool - able to cross cut, do dados, rip cut, cut moldings and more - some tasks requiring different cutters and jigs
My first home shop saw was a top-of-the-line Craftsman RAS (made by Emerson Electric) - that I quickly grew out of - all but replaced by a Unisaw table saw - later on adding a sliding compound miter saw. At the time I bought my RAS in the 1970’s - Sears probably sold something like 10 models. Now the tool has pretty much disappeared from manufacturer’s lineups - mostly replaced by miter saws and table saws.
Dewalt, I believe the inventor of the tool, no longer makes them. Acquired by Black & Decker - Dewalt was successfully turned into B&D’s flagship small power tool (no hand tools as well) brand. The Dewalt transformation really rescued the parent company’s position in the business - it having been severely tarnished by having the B&D name put on lots of orangey-plastic tools of sometimes dubious quality aimed at the DIY market.
The Dewalt-style saw is still produced:
