For used auctions (for things with demand) figure about 75-25% new prices.
If there is a glut, sometimes you’d end up with just price per lb. (Often just a couple dollars per).
About 10-20% below local used prices is what I’ve seen though sometimes they go above (bidding frenzy?).
Just some of those espresso machines are $10K [1] and $25K [2] each.
Freezer is $24K.
Of course, all these are "new" prices.
