I work at a game store, I say buy one of the bigger models if you can get one. Its not the size that makes it unreliable its the parts, remeber that the sytem dropped 100 dollars, so they must have taken the quality out to do so, we have got 1-2 of them back already for not working. Also remember that ones with 4 usb ports are better made, and play ps2 games, but all of the larger models should be fine they have a less than 5% defect rate.
