Hello
Hunter1 - if not already done, I would urge you to look at the regular sized iPads (9.7") vs. the Minis (7.9") - if you're planning to do a lot of reading on the iPad (especially magazine subscriptions), then the larger screen and retina display (particularly w/ 'older' eyes) may be preferable? My wife has the Mini and does not subscribe to magazines, but I do on my iPad 2 (soon to be replaced w/ an iPad Air 2).
Now if indeed you want a newer Mini, depends on your budget (and if important, then consider refurbished models from Apple) and needs, particularly the amount of storage desired and the need for a cellular plan - please look at the model specs comparison
HERE. For myself, I would go w/ either the iPad Mini 2 or 3 - both offer a retina display and the A7/M7 processors, plus the Mini 3 has fingerprint technology, so I would favor the Mini 3. As to storage, I would be reluctant to purchase a device w/ only 16 GBs on board, so 32 or 64 GBs would be my considerations.
I'm sure that you'll receive other opinions, but just my thoughts. Dave
P.S. Looks like I was 'beaten to the punch' - LOL!
