My first stop would be a Sketchup designed, laser cut mitre guage. 
However if you have mastered bowl turning, you'd be crazy enough to make your own mitre slide to fit to any reasonable mitre gauge... even an Incra.

As you have asked for upgrades and other non-related feedback....

Upgrading from a Triton 2000 Workcentre,
(which was upgraded from a Triton MK.II... g'donya George),  not really knowing what I was doing
I bought what was then classed affectionately as "contractor's saw",

before I was banned from the big smoke and forced into cohabiting with the rabble in downtown Churchill... so pottzy, you're banishment from LJ is back page news)... which makes it about 16+ years old.

It has a sliding table on the left and that poopsie fence was quickly replaced by a more functional Biesemeyer style fence. Naturally, wheel were a must, which should've been the move before the assembly... amounting after,

was a pain... but i was a

green novice.

Over the years, I have gotten rid of that framework base, added a router table extension and provided some better under table storage,

to the point that I now consider it as a full sized tablesaw.

Unfortunately, I cannot spruik the saw as it has been discontinued.  IT was one of those generic styles that came off a Taiwanese production line and branded by anyone that had a few shekels to spare. Unfortunately it was a bloody great saw and upon re-evaluation by manufacturers/suppliers, when the cost was raised to what it was actually worth, no one was prepared to pay that much for a non-full sized saw (at least that was the rumours in the trade).... so dream on and if you can find a 2nd. hand one I would recommend it
Bottom line is that a good tablesaw is what you morph your purchase into.  Off your rrs and make a timber mitre slide. All saws have their pros and cons and probably most owners will say theirs is the best, but it's what you make of it that makes it good (and unique).

However, in my humble opinion, if you must pick a brand, it has to be SawStop. With it's foibles and countless premature ejacu. tripping reports, a few hundred shekels is not a great sacrifice for that avoidance of medical intervention that can add a few 0's to the end of what many considered excessive wasted shekels.

A for the axe on top of the tablesaw,

Here in Aussieland, guns are banned and there are many home invasions by young recidivating thugs armed with machetes.  I think I can better protect myself with a Tormek razor sharpened,

than my bare arms.

If your first cut is too short... Take the second cut from the longer end... LBD
