I wouldn't get one until you could upgrade the Hard Drive with an off the shelf.
500 gigs is nothing with the size of games these days.
More importantly, if the hard drive breaks (as they often do) your $500 console becomes a brick.
I think not allowing users to upgrade the HD was a very shortsighted and stupid move by MS, especialy considering that their initial intention was to allow users to play everything off the HD without a disc but with DRM.
