I have that same saw and it's okay but beware the pivot pin that holds the saw to the base.
It has a tendency to work it's way out.
As for paying that kind of money for a used saw I don't know.
My neighbor just bought this saw for $99 on sale and for the life of me I really can't find anything wrong with it.
It even comes with a 40-tooth thin-kerf carbide blade.
I suppose if you are going to use it all the time at work it may pay to go with a brand-name tool but otherwise I would go for value.
