Two years ago I was going through the same decision making process that you are now Jonathan. I was trying to understand the differences between the Grizzly 691 and 1023 while at the same time comparing them to the high end saws. At some point I realized that I was actually considering spending $3K on a table saw! With that realization the choice became very clear. I bought the G0623X. The incremental improvement per dollar in capability for the slider was enormously greater than that for the high end saws, although this depends somewhat upon your valuation of the sawstop safety feature.
