For me I wouldn’t change it. I enjoy having everything together in one table. And I can use the fence on both the table saw and router. The only change I would make is the drop extension on the right I would make for just my mitre saw to again make use of the fence as a stop for boards to be cut.
Also I have added dust collection in he table as well. A small 3/4 hp collector is now in the air compressors location underneath and has a gate for each tool. The air compressor in now mounted to the wall beside the table
If you dont like what you can buy, build it.
