To be honest, craigslist. I've seen tons and tons of iPads on craigslist for lower prices than they are brand new. On eBay they are just expensive for some reason, but they are relatively cheaper at about $50-100 on each model. I saw a 64GB 3G model for roughly $700. I bought an iPad 16GB new in May and realized I didn't need it so I sold it at an ashamed price of $340 on craigslist. Hope you find one.
