I really don't like .eu domains, and neither does the market. Plus, this one has a hyphen in it which also lowers the value. I think they all L-L.eu domains are bought out, but am not sure (can anyone confirm?). That may add a little to the value, but not much probably. Does the domain get any traffic? That could be another source of value.
that is not my domain but i have a similar domain which i dont want to mention.... e.g. s-p.eu the traffic is 10 uv/month and both are premium letters
