Jack, I've had a similar setup for about a year now. The main difference is I went with the INCRA Mast-R-Lift II Lift (made by Jessem), which I really like. Other differences: I didn't get the Stock guides (looks nice) or the extra stop, and I went with a Rockler power switch.
Overall, I'm very pleased. But I have a few small nitpicks:
1) I have the LS25. Note that even on the big table, to get the full advantage of the LS25, the base has to extend off of the table (at least 4" has to be on the table), or you have to build an extension. See p. 5 of the LS manual. So I don't take full advantage of its travel, although it's still more useable travel than the LS17.
2) I don't like the wheel set, because the fixed wheels should castor and lock. Maybe I'm just too used to my other tools, which are all on castoring wheels. I find the height adjustment is also difficult on the fixed wheels, if not impossible once the table is put together, although this is a one-time issue.
3) The Cleansweep collector works very well, but is very large. It takes up nearly half the width of the storage area under the table, and nearly the full height, once you add in the piping. I'm currently adding in drawers to the cabinet, and I decided to abandon the cleansweep, because I want more storage. I'm building something like this: INCRA Router Table Cabinet - by Lance @ LumberJocks.com ~ woodworking community
and there's no way you could have those 2 drawers under the router with the Cleansweep. Note that the cabinet above exhausts the router cavity out the rear, rather than the bottom like the Cleansweep. This saves a lot of space, and I don't know yet how well it will work. Regardless, you also need to add a tee or something in order to exhaust the fence.
4) The Incra system depends on bits that are the right size. I've had good luck with the Whiteside bits. But I have a 1/2" Freud straight bit, which is slightly (a few 0.001") undersized. An otherwise fine bit, my Freud results in too much of an interference fit for box joints, particularly with hardwoods such as maple.
5) Don't buy the shelf supports if you plan to enclose the bottom. They block the side panel inserts.
6) Finally, I like the stand, but only if you have no plans to enclose the cabinet and add drawers. If you plan to enclose the cabinet and add drawers (like I am now), I believe it'd be easier just to build an entire cabinet from scratch. YMMV.
That's all I can think of. Again, I'm very pleased and will keep this setup for a long time. Although that Sommerfeld sure looks nice
