If I were you, I'd get a PS3. Valkyria Chronicles will last you a good while. Also, you can download alot of demos on the PS3. Lastly, when you save up enough money, get yourself a game with good online multiplayer functionality so that you can always have access to the multiplayer environment. I recommend, something cheap like warhawk or a shooter like Modern Warfare 2, Killzone 2, or Uncharted 2. Tons and tons of replay value. Here's some advice, ask for an allowance =P.
