I'm been thinking about upgrading to a DS Lite for a while and now im finnally gunna do it. I currently have a Red DS Phat, How much do you think i'll get in cash or credit from a typical microplay, ebgames or gamestop? Please make sure you include what currency, thanks i don't want them to rip me off. (I don't have the strap anymore) and it's in ok condition. I've had it for a year.
