Just to keep thing in perspective...

A Delta Unisaw is "roughly" 388 lbs give or take a lb.

A Delta 34-350 is "roughly" 840 lbs give or take a lb.

Most 12" saws can use a 14" blade, which has a major
advantage over a 10" saw in depth of cut.

Most 12" saws have the "mass" to handle larger(5-7hp)
motors which can run non-stop for 8 hour shifts cutting
wood or other materials.

Most production shops will be using a power feeder for
daily runs. A 3hp can not keep up with high speed power
feeders.

A Felder or one of it's brothers would be a logical
choice for "certain" operations.

You can also still buy a real American made saw that is
quite impressive..

I'm curious why a 12" table saw is wanted? To simply get a heavier
chasis, more cast iron than is available on 10" cabinet saws? Or are
you looking at the various European models produced by Felder, Hammer,
MiniMax, Martin, etc. and 12" (300-350mm) is the standard size?

If you simply want size and weight, then you might want to move up to
the 14/16" size. I think they have a considerable amount more size and
weight than the 12" saws that are a sort of beefed up cabinet saw.
