I just bought a dsi off of ebay and while I knew that it was used I was still taken aback by the condition. I can live with it, but the screen is kind of loose and there are a few other imperfections. Now I was just going to keep it but I got the costco coupon booklet and they have 30 dollars off of the dsi xl. So what I'm wondering is it worth the forty dollar difference to return dsi( I have 14 days) and get the dsi xl?
