My two cents!
<span style="font-family: verdana, geneva;">Here is my opinion and you're likely to get a few more:</span>
<ul>
<li><span style="font-family: verdana, geneva;">Springs are all over eBay and generally you can get a set in the $20 range</span></li>
<li><span style="font-family: verdana, geneva;">Blower units are as well. Those are likely more in the $50 range but if it's just the wire it could be an easy fix that costs nothing</span></li>
<li><span style="font-family: verdana, geneva;">Yup, soap dispensers too. Maybe $30 or so depending how greedy the seller is.</span></li>
<li><span style="font-family: verdana, geneva;">The racks a bigger challenge but you could really watch for a donor machine on line in the $100 range that has better racks and maybe even good springs, blower unit and dispenser if the dispenser issue isn't a loose wire.</span></li>
<li><span style="font-family: verdana, geneva;">I think your biggest challenge is the rust spot and the mold. But honestly I have NEVER heard of mold inside a dishwasher. Have you not used it in a while?</span></li>
</ul>
<span style="font-family: verdana, geneva;">So, it really boils down to whether or not you want to challenge these few things. A picture or two of the mold and rust might help folks here to better assess how serious they are. You won't find a new machine today that's built as well, washes as well or as quickly as your KDS-60. Is this a portable or Sink combo unit? You can search Craigslist for any Kitchen Aid machine in the 20 series for the parts you need if the rust and mold aren't issues that would retire the machine and then you'd have a machine you could use for other parts as needed or just swap them out. It also depends on how much you like this machine and if it is a sink combo how much trouble it would be to get the dishwasher out. As I recall some can be a real beast to remove.</span>
