Hi guys. First thing to say is that I am not a mac user traditionally and am currently typing this on an old Lenovo laptop. I have decided to jump into the world of mac, having liked what I see. I don't want to spend a fortune so I have seen a second hand 2015 imac for sale on ebay from a local seller to me. Having done a bit of research it seems like a decent model: 21.5 inch mac, retina 4k, late 2015 3.1ghz intel core I5 8gb ram intel iris pro graphics 6200 1536mb. 480gb SSD. advertised as perfect condition with accessories. So... the question is how much would you guys pay? I have asked the guy and he said he wants £720. wondering if this is a good price? any help would be appreciated. Thanks guys Simon.
