Ok, thanks you all gentlemen 8)
So, it turns out that 1/ price dropped to €900 (posting included) and 2/ the seller offers to first send me the SG so I can check it out before we call it (or not) a deal - so at worse I'll just lose the return fee. Also he's interested in my Vox Standard 25 (which I would have sold to fund the SG anyway), so I'm going to give it a try ;)
