I have the GMF and so have both bases and I don't like it one bit as far as a router lift goes but it's sadly all i have. And now it has started messing with me and I can't use the fine adjustment anymore to adjust it upwards, only downwards.
I would rather use it as a hand held router with the fixed base. I was hoping for some 3rd party router lift that could work with the bosch limitation that is the power switch idiocy.
I have a much better home built lift that I cannot use either because of the switch business. I have looked into buying the switch and making my own adapter, but bosch says it's not available from their spare parts website.
