So I was recently given a DS Lite by someone, but the shell and top screen are in pretty poor shape. Since I like tinkering with hardware, I want to turn it into a pet project by giving it a brand new shell and getting a new upper screen. Problem is, it's hard to tell which parts are good and which are bad. For those of you familiar with buying these things, can you show me where I can get them and be sure of the quality?
