Nintendo DS screen replacement

DO NOT - EVER - UNDER ANY CIRCUMSTANCES - REPLACE A DS TOUCH SCREEN YOURSELF. Let me explain. 's DS' touch screen wasn't calibrating anymore, a known issue. Sadly it's out of warranty, so she found some replacement instructions, and we decided to move my touch screen to her DS. Sadly, while the instructions are rather easy to follow, the touch screens aren't really designed to be usable once removed. I might be able to get a new one to work, but at this point my DS' power and volume switches have broken off. Now I have to buy her a new DS (probably going to trade mine in and I'll take hers, even if it is pink).
