I've used a PC890 with a mounted fixed table base and an extra plunge base for a couple years. Now I'm looking at the Freud in Woodcraft's black friday deal so I can just mount that and have the PC890 to use as a handheld. Buying that would mean getting a new router plate as well, which got me looking at router lifts instead (this is a vicious cycle...).
This is all a long background to get to my real question - why buy a router lift if all of these routers come with above the table height adjustment and bit changes? A lot of people seem to be spending $300 on these things, so I figure there must be a reason. But since I've never used one, I'm hoping somebody can educate me. What am I missing?
