I've had the Incra TS-LS (Table Saw rail system) for 5 years, and am a believer in Incra solutions, properly applied. It is dead accurate, repeatable, very reliable - you can throw away your tape measure. Mark Mueller, at Incra, has been very helpful in working through different alternatives; though, it does finally rest on one's desire to pay the 'freight' associated with Incra solutions. It is expensive once! In addition to the TS-LS system, you would have to purchase the Wonder Fence, as well.
Certainly, there are alternatives to Incra tables - I believe that most Forum members could build and install a very acceptable table.
