Panelling jigs < sleds> are easy enough to
build, as are tenoning jigs
etc. I'd spend the money on a good counterweighted, air sucking,
power interlocking blade guard.
Get a good Stacking
dado kit, no wobble blades, < especially if you plan on using them on a radio alarm saw>, a feather board < also called finger board> retatining kit is a good investment.
Seems to me, most of what a table saw does in a scenic shop is rip, while it's nice to have all the bells and whistles that go with a Uni-saw, I think you biggest investments should be for
safety and material handling, ie a really big receiving table, rollers
etc.
