Gents, just be aware of MDA DB9801 supplement 2. secondly, if you dispose of your equipment via the DSA they take on all subsequent liability. Equipment is refurbished via independent contractors correctly disposed of i.e. no land fill or finding its way onto EBAY, the trust then recieve direct payment in return, post sale.
You could of course go via that tried and tested route of auction houses and recieve very little in return, with liability and therefore pottential litigation cases biting your arse some years from now.
