Heads up to anyone considering Marc Sommerfeld's router table ... DON'T !
Being a cabinet-maker, you'd think he'd have some regard for the tolerances in the product bearing his name.
Here are just a few of the frustrating flaws [design and manufacturing]:
 the table top is composed of three sections which are +/- 0.060" different in length;
 the three sections mate via side-to-side tongue-and-groove ... but once tightened, there's an unacceptable crown front-to-back ... on my table the rear edge is 0.060" lower than the centerline and the front edge is 0.030" lower ... each section appears to be perfectly flat so the flaw is with the T&G tolerances/design;
 in the manufacturing process, the pilot holes used to insert the wire for EDM cutting the sections to length creates a surface flaw [a sharp "mound" on the worksurface] which must be ground down to be usable.
These are just three of many flaws and they should be enough for any prospective customer to choose something else.
I've called and written Marc ... but he's turned a deaf ear.
Bottom line ... you'd do better planing and jointing up some 2x12's.
