I bought two broken white DS's from the local classifieds for $50. I was able to repair the first one real easy. When I opened the case, a small surface mount inductor -- L2 (next to power switch) -- fell out. I soldered the bad boy back in and the thing works great! So I got my $50 worth. I used the other one to replace my broken power switch on my own DS, and selling the rest on eBay. Much thanks to Sean for his soldering skills with that switch.
It's fun work. I wish I had the monies to start …
