It was from ebay iirc, my purchase history doesn't show it anymore if it was from there. The local EB Games/JB Hi-fi stores were charging more than that for the unit only ($120-$150), plus it was in like-new condition and came with a bunch of assesories so I didn't mind too much. I know it wasn't the best, but I was specifically looking for a 1000 as everything I could find at the time implied that the later models weren't easily hackable, so for my first time it seemed good
I ended up sniping a deal on a GO about 2 months ago so it's mainly a backup now or for my younger brother to play on sometimes.
I got my 1000 with 6 games, a couple of cases and a little stand for £40 from a friend, which was and in my opinion still is a fantastic deal. I still have it, and with it being a 1000, it means I can also use it as a backup remote control thanks to the infrared port.
