I bought an used DS Lite off ebay for pretty cheap (70$). I figured, I only want it for a couple games so it's not worth buying a new one for almost twice the amount. I just received it today and after playing Phantasy Star Zero, I noticed that the R & L buttons don't work (go figure right?). I don't really feel like going through the trouble of returning the product though if the L & R buttons don't have much impact on game play. I'll probably play zelda, pokemon, phantasy star, mario, and harvest moon. Other than that, I'm more into PC/xbox360 gaming. So should I return it or ignore it?
