I am new to woodworking, been using a bosch 4100 portable table saw I bought from a neighbor, but have found I need to to upgrade. I have a chance to buy a used saw stop 1.75 hrs 30" pro series cabinet saw it is 2 years old and used by hobbyist who has since passed away. It includes wheeled base and blade guard with the built in dust collector. Only problem I see is 4 rust spots on table about the size of a quarter. Lowest they will go is $1600.00 Any help would be greatly appreciated and thank in advance.
