Okay, I know I said I was only going to buy one game this month (Kirby Collection for Wii)..... And that's technically still true, because this isn't a game.
A fantastic condition used DSiXL (Midnight Blue) popped up on my radar for around $70, and I couldn't help but grab it. It doesn't have the larger, pen-size stylus, but is otherwise perfect.
Not sure at the moment if I'm going to flip it to get more games, or keep it and maybe sell my DS Lite... Or keep both... Lots of options.
