Is the original Incra jig and fence all that is necessary in real-life, and
the improvements just over-engineered and well-marketed hype?

Should I give up routing and just nail rough timber together into crude rain
shelters to keep the awful British weather at bay as we all live in mud huts
and talk funny over here and haven't got any power for our tools anyway?

I have the original Incra jig and I wasn't impressed with its use on a
router table. I stil occasionally use it as a guide to repositioning my
tablesaw rip fence.

The high priced rigs do the job, but if you only use the capabilities
occaionally it'll take a while to recover the cost.

If your router table has a miter slot, you can easily rig up a dial
indicator or the like that rides on the miter slot and can ensure the
fence is parallel to the slot. Would that do the job for you?
