I thought that already existed. I aint looked at router lifts but thats what i expected if i am gonna shell out this kinda dough to just raise and lower the lift. I get a little testy with my pc router and its built in lift adjustment however i aint a production shop and for less than the price of one of these lifts i got a variable speed 2hp router and two bases. One fixed and one plunge with an top of table height adjustment and two collects to boot.
