Domain name Breeze-block-shock!

I very nearly pushed a breeze block out of a small hole that would have proven most painful! ‘Why?’ I hear you all shouting in unison. Well, I shall tell you! After considering the possibility of changing the name of our boat, I decided to see if the webname was available (This is secret stuff at the moment!) and I found that it was held by a domain name warehouse. The minimum offer I could make was $500 which I duly did. They have come back and asked that we pay $2500 for the name… no hosting either!! I quite clearly stated that it was for personal use and a way to get some info about the boat online. How can they expect a mere mortal (Normal person with bills and a boat refit) to afford that?
