If you can get the core system for that price then I'd say get that and buy what else you need later cuz you'll still be saving money. Headset isn't necessary, the wireless controllers are nice but again not necessary, and component cables can be had at most places. The hdd lets you save games but w/out it you need a memory card which is kinda pricey anyways. You can't play original xbox games w/out the hdd, and you can run game images from the hdd and allow you to not use the disc. Well actually at this moment I don't think you can do THAT just yet on the xbox360, but it won't be long till you can.
