I have a Used One that I got from GameStop. My only gripe is sometimes it won't read Blu-Ray Movies on the first go and I have to eject and re-insert the disc.
I will look into this a bit for ya. If the dollar amount is too high for a one time purchase, you should think about getting a "Bill Me Later" account added to your PayPal account (if you have PayPal). That's how I got my Nexus 7 tablet from Walmart.
