We have only ever purchase, since the iPad came out, Apple refurbished or a used product on Swappa that still has some Apple warranty left. Swappa is a great source of used products, and, we only ever buy mint condition stuff. Got an iPad pro for 30% of list price as an example in mint condition with warranty remaining, which allows me to get a problem resolves if there is one. You have to be patient and wait for the right unit the used method. For the refurb method, you buy and go. Same warranty, and you can even add Applecare. We've probably purchased around a dozen used or refurbs over the years. And then we end up selling them when we "upgrade". Some of them have cost us $0, as, we sold them for the same amount we purchased them for.
