I bought this table saw last December while visiting relatives in Austin, TX.  The table did not have the cast iron table extensions, but the price was right.  I made my first ever eBAY purchase a few weeks ago and bought the table extensions.  they came this week and I added tom on the saw today.  Before adding the extensions I wanted to add some lockable wheels so that I can move the heavy saw around.

Saw with the new wheels
New wheel with the old stand off on the ground.
