How about the Makita RT0700CX4. I have the RT0701C which is the 110V equivalent. You are lucky in the UK, using 220V lowers the current for the same power. There are mounts available on Thingiverse for this router and it has the benefit of variable speed. It’s about 96 pounds on Amazon. Weight is listed as 3Kg so its probably on the top end but it is rated at 700w and should cut quite well.
