I agree with Seth 100%
I feel it also depends on how many festools you own (seriously stay with me on this )
and how well you know how to use them.
What I mean by that is remember festool is a SYSTEM. If your system is incomplete then you cant do everything using the system.
You can do this and that but not everything.
Im making a walnut media center right now.
I used the PGs to rip 20mm edging for the ply.
Used Tom's technique from his ripping in the field thread, I ripped the 2 1/4" cabinet door stock accurately with no issues and easy as using a table saw.
The non festool tools I used were
18 ga nail gun, router bits, bessey bar clamps, bessey toggle clamps(hold down jig ), general finishes stain and laquer and my spray gun.
As you can see very few non festools were used.
Please note this was all done in the shop.
So what Im basically saying you can get away without owning a table saw.
Sometimes it takes some creativity to get the work done
it all comes down what you are using the tools for and knowledge of how to use the tools.
Steve Base in his festool end users classes says that most people only use their tools to about 58% of their potential.
I agree with that.
As Im always learning new things about the tools, both in the classes / demos, here (FOG) and utube , talking to other guys who have the system and occasionally I even have a idea.
Since Im moving and will have a small shop. I'm getting rid of all my stationary tools, table saw, 6" jointer, drill press, cast iron router table, PC 690 router, PC 7815 router, pc hand power planer, biscuit jointer, small ryobi mini biscuit jointer and other tools, have replaced them with festools. I havent used them in a very long time.
I havent had a need to use these tools since Ive gotten a large portion of festools and learned to use their system.
To me its not a pick and chose thing, when it comes to a question of whether you need a table saw or not.
Either you use the entire system or not. if you mix and match then yes you will need a table saw mixed in with your various tools.
I can build everything I need to using my festools.
things like a multimaster, hammer drills, sawsalls , nail guns etc obviously festools cant replace those.
But for the most part. What I build I can use festools.
I am not a full time pro, I am more like a splinter maker, wood dust maker, scrap pile builder. I do make scrap wood for folks on the side.
neighbors friends relative etc
Relax guys all those tools that Im getting rid of are either gone by now or spoken for.
This is all my opinion, your milage ay vary
