OK, so I went with the Accurate Technologies Digifence. As with the Wixey, you have to drill a few holes through the hardened steel rail. Well, 6 drill bits later, and I gave up and epoxied and fiberglassed the parts to the rail. God I hate drilling into hardened steel. I clearly don't know what I am doing with that, despite reading as much as I could on Google.
We'll see how accurate it is. A little bulkier than the Wixey, and a little finickier to install. Plus I had to work around my microadjuster, which thankfully was possible.
Hopefully I'll like it a lot.
Here's a few pictures:

So now I have digital readouts on my planer, tablesaw, and wide belt sander. Geek-like?? I'm sure. But much happier this way. Bandsaw next? Panel saw?
