I regret not buying a stash of 2012 Macbook Pros and hoarding them for my own use. Edit: And iPhone SEs as well
My MBP 2012 has had 6 SATA flex cable replacements by Apple in 3.5 years (I bought mine in 2015). The last few repairs have all been ~3 months apart. It's easily the most unreliable laptop I've ever owned. Thankfully Apple did all the SATA cable replacements free as required by law in Australia.
That said, you should be able to find mid-2012s for about $450 - $650 US refurbished from mom & pop Mac repair stores. [2]
