I've just bought the system with the taller fence (
102426) to put on my old TS 200. It's identical to the one mentioned above apart from having a taller, longer fence, and an extra, simple back rail to support the end of that. The construction makes it pretty easy to use something different as the actual fence if you wish, or fit a sacrificial one (long fences generally not being a wonderful idea'n'all, for safety reasons). The tall fence will also attach laying flat, which might be handy for some operations (but a shorter fence is always safer).
It would be nice if Axminster sold the smaller cross section fence as an option, because having both would be handy. But not essential...
... Looking at pics of your Sheppach on-line, I can't see why either of the two Axy aftermarket ones shouldn't fit easily and well. I have to say the instructions that came with mine were poor (unusual for Axminster!), but that's easily fixed with some careful measuring: You just make a pair of holes in the edge of the table (either tapped or through holes).
There are two angle brackets, which hold the rail for the carriage. The rail is easily detachable from the saw once set up, and it doesn't matter within reason where you choose to fit the brackets - anywhere along the edge of the table that suits you.
It's a bit more of a faff on the TS 200, as that has a flange on the front and back edges of the table (for fitting the rails for its own fence system). The flange gets in the way of the brackets. So I either get a hacksaw to it and cut notches in it where the brackets will drop down past it, or contrive something else.
On balance I'm pleased with it, but still mulling over the fixing options, but that is a TS200-specific problem.

PS: It's a tall fence as it's really for resawing operations on a bandsaw. I'm fitting a second one to the bandsaw at the same time - bought two identical ones.
