I just sold my 14" Delta because it really wasn't up to cutting big turning
blocks. So now I am under the gun to order its 3hp replacement.

The two choices seem to be the 19" Grizzly and the 18" Jet. Any reason to
pay a few hundred more for the Jet?
(I am planning on the old Grizzly 19" because it is cheaper than the new
ones. The main differance seems to be the cast iron trunnions, but those
can't be worth $200, can they?)
I know the Rikon is well regarded, but they don't seem to have a 3hp.

There are better saws out there for bigger bucks, but if I use it 50 hours a
year that will be a lot; so industrial quality would not be a good
investment.
