Ok, I know there are probably some posts on this already, but wanted some new opinions. I have a Unisaw with the 52" unifence. Is it worth the money to upgrade to the Biesemeyer fence system?

I have no problems with my unifence. It cuts perfectly square and I have it zeroed in perfectly. The only thing is because of it's design, it is hard or impossible to use some basic fence mounted jigs. I always find a way around using them, but for safety reasons I would like to be able to attach a featherboard jig to keep the stock pressed down against the table but pretty much impossible with the design. And it's aluminum so the magnetic featherboards are out.

So is it worth the $$$ to go with the Biesemeyer?
