All of the router lift devices you find stem from the first design to make the PC 7518 easier to use in a table. Most lifting devices make it possible to change bits above the table. I believe both of these models are still made in the US, but that will change. Almost all routers are manufactured in south east asia now. Triton and Festool are the exceptions. There are plans for building your own lift, and plans for a tilt top table on this site; both are good options. Of course as long as your router is plate mounted it is a simple enough matter to pop it out of the table for bit changes and adjustments. This is Bob and Ricks "Simple is better" method. The best reason for buying a router lift is limited use of your arms. Is lifting the router out of the table for bit changes and adjustments as easy? No, but remember this way you will not spend your life turning a crank either.
