Some posts here concern whether to buy new or used mac minis. To keep things real I thought to post actual data for recent sales at eBay. Late 2012 low-range dual-i5 4GB 0.5TB HDD. Someone recently sold seven of these in quick succession. The selling prices ranged from $404 to $455 with an average (mean and median) of $421. The original cost from Apple was $600. Late 2012 mid-range quad-i7 16GB (upgrade from 4GB) 1TB HDD. Someone recently sold two of these in quick succession. The selling price was $730 each. The 16GB upgrade is now $100 from Crucial, so taking that off, the price of the mid-range 2012 model is $630. The original cost from Apple with 4GB was $800. Keep in mind eBay has lots of used car salesmen asking more for these machines, and the dynamics of auctions can lead inexperienced buyers to overpay. I think the values above are realistic because they were multiple sales.
