Reg Fee, the domain doesn't really carry asset value with it. What type of market could big zeno apply to? Zeno gambling? Zeno acne? Zeno watches? It's not specific.
Think the only worth that the domain would have would be if it was made into something along the lines of the Shoemoney blog that is running at the moment, covering everything rather than one subject. $xx is its worth.
Thanks for your views. This was actually registered as a mistake - my wife misheard the name bigvino.com over the phone. I kind of like the name - I think it's catchy and quite 'brandable'... I may well end up keeping it and developing something on it.
