That's not the cutter the G0543 uses, though. Maybe they're for a
previous model? The spiral head cutters are new, and they've been
increasing the number of models with them over the years (you can get
a 6" spiral jointer now too).
In fact, the G9961 calls for H5307 cutters in the 2004 catalog, not
the H2334 you link to. I suspect they've just been upgraded.
As for the 8" spiral jointer, the folks at Grizzly say they haven't
even started getting them in yet, so I doubt they'll be discontinuing
them yet ;-)
