Yeah, especially if you work that job you told us about, dude. I'd go for a new one myself, but that's just me. Just make sure if you do pickup a second hand PS2 NA, that's working properly. And get a receipt. I highly doubt that you will get more than 3 months warranty on a second hand unit. But hey, as long as it works then who gives a flying Panda.
Edit: Jinko told me that you can also pick these up dirt cheap on EBAY. I wouldn't know, I never go there.
