I have 2 1617s, one kit, the other just the motor which was in a lift. Since then I've put a Triton TRA001 in the table, so I now keep a motor in each base. One other thing I like about the Bosch are all the great quality accessories, including dust collection. What I don't like about the Bosch is the switch on the top edge. I do like the ball handles on the fixed base. I had a foot switch on it when it was in the table. The plunge base handles are nice and beefy. It is odd that you need two adapters to use Porter Cable guide bushings, but they are solid once installed. The Bosch bushings are made of steel, and I'd prefer brass. Bosch bushings work just fine, you just don't have the variety without the adapter. For example, bushings with a short collar for working with thin templates. That's my two bits..
The more I do, the less I accomplish.
