Definately Delta. I bought the Unisaw 3 years ago and it had a 0.01
dip in the middle of the main table. I called and they sent a
replacement even though it was within spec. They did not even want the
"warped" one returned. I cannot bear to throw out the old table top
but have not found a use for it yet. The new top was within 0.004"
which is plenty good enough.
