[quote name='GUNNM']You probably wouldn't need a HD. In game saving was a really low amount of memory and arcades have built in 256 MB of memory, but if you wanted to install the game to your HD, you would.
edit: ''If your XBox 360 Arcade console was purchased prior to fall 2008, you will have a 256 MB memory card to save your games. Consoles purchased before summer 2009 will have 256 MB internal memory, and those purchased after summer 2009 will have 512 MB internal memory. ''
You can install it as well then.[/QUOTE]
Hopefully I can snag an awesome deal on an arcade model. For obvious reasons, I'm reluctant to purchase one off of craigslist, unless I knew for sure I was getting a Jasper model.
