I'm thinking about remodeling my table-mounted router rig. That gets me to thinking about router lifts. As best I understand, a lift offers two things: above-the-table height adjustment, and above-the-table bit changes. Five years ago, the only way to get those functions was a lift. However, there are now several routers with above-the-table height adjustment (e.g. the Milwaukee 5625), and a few with above-the-table bit changes (e.g. the Triton MOF001). Presuming I buy one of these newer routers, it seems that a lift offers no additional functionality. Am I misunderstanding something here?
