Summarize the following:
Sites like Amazon, Cell Phone City and Gazelle usually offer pretty good deals on used or refurbished iPads. There isn't a chance to haggle, but there may be no need if the price is right. Fixed price websites often offer accessories with the iPad to sweeten the deal, when auction sites may not. So you may be getting more bang for your buck if you opt for a site like Amazon. The Apple Store offers refurbished and used iPads for customers on their website, here. Apple has rave reviews about how well their refurbished and used iPads work, but they can be a little more expensive than if you bought from another seller. If you buy through Apple and end up spending a little more money than you would have if you bought from another seller, you'll still be paying less than you would for a brand new iPad — and you'll be paying for quality. Since bidders are the ones who set the price for the iPad, this could give you the opportunity to purchase it for a great deal. The fewer people who bid on the iPad, the more likely you are to buy the iPad for less money. If you're really strapped for cash, this could be the best option. Whether you're picking up a used iPad from someone on Craig's List or if you're getting one at Best Buy, in-person purchases allow you to make sure the iPad is in good condition. Sometimes, you may even be able to haggle down the price if the seller is right in front of you and knows you're looking to buy.

Summary:
Buy from a fixed price website. Buy from Apple. Buy from an auction website like Ebay. Buy from local, in person sellers or big box stores.
