The 520 Pro Fence and Table System Upgrade does not replace the table. It just replaces the round pipe rails with extruded rails, the fence, and a few other parts and pieces.

I can't say the 510 fence gives me any real problems. It works ok, not great but it is square the blade and table. Seems to work fine. But I've never tried the 520 Pro Fence.
I have used a friends table saw with a Biesemeyer fence and it was very nice. Is the 520 Pro Fence on par with high-end aftermarket table saw fences?
The 510 table upgrade was a huge step-up from the smaller 500 table, but I'm not sure the 520 Fence Upgrade is worth the $520.
Tell me why you think the Fence Upgrade is worth it.
(Does anybody else think that Shopsmith prices their stuff way to high?)
