I'm planning for a Sawstop purchase and am trying to figure out best route for dust collection. At $450 for the floating arm, it prompted me to look at aftermarket options.

The Excalibur (General Industries) and Exactor look to be very similar to Sawstop's floating guard. I can't find anybody selling either of those... have they been discontinued?

Any other options I should look at? PSI has one, but reviews are pretty iffy.

Or am I overthinking this and should stick with the OEM overarm or floating guard?
