In all honesty just save what you can when you can and you'll be surprised what you can afford. I never thought I could afford anything on what I make now, but I've got a laptop for college, a fairly powerful gaming computer, a file server, and a car now ('05 VW GTI 1.8T, mmmm turbo noises). Just have to cut back what you think you can live without and SAVE EVERY PENNY. Make your own meals every day, don't eat out, etc.
Sorry mods, I know I know, save it for the chat thread.
