I agree completely with all of you.
Frankly if I was really wealthy, my setup would be a sawstop for parallel rip cuts and a full euro slider for all other tablesaw cuts. But alas, I have resource constraints. So the best of both worlds would be a sawstop with a cast iron table and a biesemeyer style rip fence with a full outrigger euro style sliding table.
I paid a little over $3k for my sawstop PCS, and also bought an excalibur sliding table. I bought the excalibur used at an awesome price. But let's pretend I bought it new. Current prices are around $1,400. So all in, this setup brand new would cost $4,400, plus tax/etc. Let's call it $5k.
Hammer's K3 winner (79 x 48) is selling for $5k on their site. A sawstop sells at maybe a $1k premium over similarly equipped competing saws. So let's assume the same mark-up applies here. I'd definitely pay $6k for a sawstop slider. I'd have to sell my existing saw and pinch my pennies for a while, but I would totally do it.
