Just had to provide another chuckle at the elephant - poor fellow is just looking for a few peanuts...
The used market really gets down to moving the equipment into the hands of a different economic layer; there are many more photographers who would like to shoot medium-format in the sub-$6000 range than sub-$10000 range. For all the same reasons - better color, better detail, better first-appearances with better camera, etc. They are willing to tolerate the few nicks and scratches and not the largest file size and will often trade-up within 12-24 months.
Where there are buyers, there are sellers.
When we execute a trade-in, in some cases, we can help the seller obtain a greater price for their equipment than the standard trade-in credit direct from Hasselblad; in other cases the trade-in credit is greater and it makes sense to take advantage of the trade-in offer.
Hasselblad then cleans and refurbishes those trade-in units that are feasible reconditioned models. Some units are beat up so badly, they are not suitable for re-release.
I'm not complaining, just reporting
