I'd love to, but I am suffering from a lack of $$ at the moment.
That is sad. It's like a having to choose between bread and water. You'll die quicker without water so get a DS. You'll still die eventually without bread (which you also lack at the moment), so save up and get a PSP as soon as possible. The DS is the best handheld and the PSP is an awesome multi-media device (w/some great games). I highly recommend both.
