Which should I get? i, or Lite?

Please note that before making a decision money is the MAIN factor in all of this.

I bought an orignal DS around about launch time. Last January I sold it. I now want another DS. With the impeding release of the DSi, I can't help but want one. But I won't be able to get one on launch (which is my intention). I generally just want something better than the original so the DS Lite is another great idea. Cheaper than the DSi, and better than the DS (plus, it allows GBA play). Which should I get? A DS Lite as soon as, or an i a while after launch and with some features I may not need? Is the DSi screen noticably brighter/longer battery?

Please dont just post with 'get the i coz it rox', I would like decent help with my problem. Thanks! :D

Sorry, didnt see the sticky. Closed.

Please use the DSi vs DS lite --- DSi Discussion Thread
