Its going to be difficult to ascertain a value. Germany has a strong ccTLD (if not the strongest) and it would be better suited as Satze.de - It does appear to be taken and have a website (although just a black background).
Interestingly enough - there is also the .net version which is developed into an asian website. I'd say you have a few routes to go on this one, but overall value is going to be solely dependent on what someons going to pay for it. I realistically dont see this one fetching more than low xx (just over reg fee). Its difficult to spell and recall, best of luck!
