        The chips for the upgrade aren't that expensive to buy for the 
ST you need 14 of them I believe and they run you from 2.00-4.00 bucks 
each...Also you had better check what type of board you got...ther are
3 different kinds for the 520...
        1) you can only piggyback the chips on top of each other
        this one requires alot of work..and a steady hand

        2) the holes are pre drilled into the board and yuo have to 
        use a deslodering Iron then stick the chips in and solder them 
        back in (this is what I have)

        3)the 1040/520 board that all you do is plug in the chips and
        solder in the resistors

        I personally am geting mine upgrade to a meg for $100.00 
including parts and labor since it takes a lot of work to solder the chips 
in and when I figured it out it was only 45 dollars in labor 
which wasnt bad
                                hope this helps out a little bit
