With cable between 600 and 650.
Without cable between 550 and 600.

You might get more, depending on general availability.
Note that with the standard cable, match on 60 meters is not really 
feasible.
With an extra wire, it is.

I sold mine last year with the extra wire in a custom cable for $600.
