Given the price when new and presuming it is in good order for a quick sale £800 . If you are prepared to wait £900 - 1000 .
New price from the link was £1,095. A quick sale at £800? Really?
Some on here have completely unrealistic views of used kit value. Ex dem kit, with proper warranty, say 70-75% of RRP. Used kit, fairly recent, c\w packaging accessories, etc then 50-65% (latter on a good day). 35-50% for most else. Some items/brands will be different, particularly if sought after and in short supply.
It always amazes me what many list on here at, with a description of something like 'only 6 months old, blah, blah and you can have it for 10% less than RRP'. That's fine, but watch your item not sell for months or years (look in the classifieds for examples).
We all like to think we're great buyers and can spot a bargain. Well, wakey wakey, so can most others! On top of which who pays full RRP? I often see items on here and elsewhere that I know I can buy brand new for often less than the posted used price.
Still, this is a subject that is opinion and just like a**eh*l*s, we've all got one!
Carry on
