Thanks Steve - I contacted Makita UK and they have confirmed that the bases are compatible, happy days. I won't be able to resist the temptation to buy a cordless body now to maximise my gadgetry. I really like the RTO700CX3 router, it manages all my hand-held routing and is as good as my reliable old Bosch.If not John contact Makita directly and get some advice.
