Like Hornbeam I recently bought a complete Jessem table from wwworkshop. I've made many over the last nearly 50 years. Everything from a sheet of chipboard and 1/2in router with an oak batten for a fence, to a nice cabinet with a decent fence, and culminating in the Jessem table setup. I justified it since I had just started a job and my existing router and inverter failed. I was up against the clock and needed something quickly with fine adjustment. Although very expensive the job has paid for it. I'm very happy with it and if as your handle suggests, you're using it commercially then I would say it's easily justifiable.
It's good quality and easy to use, but only you can decide if it's worth it.
