I'm a fan of Bosch. Their 1617 EVSPK kit has fixed and plunge base. Been around for awhile and parts and service/support is top of the heap. A lot of us here really like them. and for about $60 you can buy a separate base you install in the table and can adjust height from above the table. You pull the motor out of the hand-held base, insert it into the table base and you've got a great table routing setup. I just don't think you can beat the 1617.
