Buy the cheapest one you can. We have 4 ds' floating around here somewhere, and probably 100 games. . They get sucked into the vacuum, you find them in the couch. we bought all our kids one the day they came out(ds not ds1) and they didnt play them after a week. My one son has a psp that he likes better but it doesnt work and I dont think he would play it if it did. Buy a good used ds.
