I too struggled with the pricing of the supplies.  I was fortunate to locate a few on Ebay relatively cheap and was also able to repair the failed ones I had.  In one case, I actually purchased an entire DS10 system for less than the cost of the supply.  Contact me via Email if you need one at a reasonable price.

The main problem with these (and other vendor specific supplies) is that the connectors are unique to the vendor.  The power supply itself is perhaps designed with a tighter tolerance or more safety features, but overall the supply is still a switch mode supply with all kinds of regulation and control.  THe failures I have seen thus far have been relatively simple to fix.  Please note that these repairs are not typically DIY repairs.  I have been in the repair business for a long time and these are not new to me.  Parts are getting a bit difficult to locate outside of larger suppliers that require minimum purchases either by count (1000 pieces) or by $$ ($300-$500 purchase).
