Iwata WS400 Evo for sale

Brand new and unused except for thinners flush. Special edition in carry case. 1.3mm needle & nozzle. Iwata regulator included. Bought in error, I thought it was an HVLP and my compressor needs to be bigger to power it. Paid €780, bought from Spray Guns Direct in the UK. I have paperwork. I'm getting a good few offers in the €350 range and this is not acceptable to me bearing in mind that it's unused, in its case and cost more than twice that. If that's all people are prepared to pay, then I'll hold on to it.
