I have it. I like it. I think I have an older model and they are the same except whatever the one difference is.
However big you think it is, it's a little bit bigger so wherever you plan to store it, it won't fit. Mine sits on the floor, and actually gets run on the floor most of the time. I'm not very tall, but you'd have to be 7ft tall to use this on a counter height bench.
you will need featherboards since it comes with none. How many? No matter the router table, the answer is the same; more. Depending how tall a piece you rout you could approach your cost for the table, with your cost of the featherboards if you buy them from kreg. The HF ones aren't perfect, but I am dealing with them.
Something on that table needs proprietary sized toilet bolts. I forget what specifically, I think it's one of the channels on the fence. Nearly every other router table uses carriage bolts so if you have featherboards or other accessories like anti kickback rollers, from another table you might not be able to work with this one without buying new hardware from kreg.
Originally I bought mine from Lowes when they clearanced it out, and planned to only use the top & fence and build my own cabinet type table. Hasn't happened yet and I needed to assemble it to rout something. The dust collection isn't strong enough with just a shop vac to pull as much as half of the dust.if the bottom were enclosed that would help a lot, and a good hood type attachment plus a stronger suction probably could get you to a much more acceptable point.
The insert is the right size if you wanted to buy a Jessem lift, I had no issue with mounting my Dewalt router to it so I assume it should take any of the common ones out there. I haven't tried the Bosch ones on it and the big PC is waiting for the Jessem lift before I install it in any table.
I tried to cover all the bases here but if you have any other questions let me know. It's not a tool I use all the time, but with a router table it's 99% setup so I have played and tweaked it plenty.
