Don't know about the Delta but I bought a Jet contractor saw with cast
wings similar to this:

with an extension table and the exacta fence at woodworker's warehouse
a few years back for about $750. Very happy with this saw and only
needed a 79¢ upgrade as described he

I know WW warehouse is closed now but I went in and showed them an ad
from a website and they met the price. Whatever local place you have
may do the same thing.

Amazon is offering 10 percent of until the 8th code="TOOLS10R"

Happy hunting!
