Larry,
Welcome to the forum!
The 892 works fine in a table, I used it in mine before I got the 7518. It was mounted in a lift so can't comment on the above-table height adjustment or bit change capabilities but it's a good router, quietest I've ever owned, smoothest start(beats the Festool 1400), and does what you'd expect for a motor of that size. Height adjustment is easy in the base hand-held with an average amount of slop. I'll hazard a guess it works about the same upside-down.
Decent tool, I use mine a lot. Not as much as my Bosch 1617 but that's because I have two bases for the Bosch, one with Pat Warner's precision base and another with his offset base with the dust catcher permanently mounted. I like the depth adjustment on the P-C a lot more than the clunky multi-step version on the Bosch, backlash is about the same, the P-C beats the Bosch hands-down in noise level and softness of start. The Bosch beats the P-C in dust collection with their accessories.
I really like the P-C collets, all their routers(except the trimmers) use the same collets and wrenches. Getting the bit out is a simple one-step operation, loosen the nut, yank the bit and you're done. Unlike almost all manufacturers which require you to loosen the nut, back it off a few turns and then apply the wrenches again for the second stage of getting your bit back. Not a big thing but it grows into a major PITA after a while, you start wondering why P-C can do it and no one else can.
Anyway, MHO is that you could do a lot worse for your money than the 892.
HTH,
Bill
