Nice 1, how much would you ask for it, if you were selling?
Bitcoin 101: your Bitcoins are only yours if you and only you know the private keys! You should never rely on a private key generated by a third party.
Very true - eight alpha/numeric take weeks and weeks to do - I have literally hundreds of words or combinations that I've searched for - alas I haven't had my graphics cards going for many months now due to the boxes age, but am planning on getting a new install with all new cards etc.
You *can* get custom ones that long done using split key. As to price... I really would have to wait until I have a new box made up and see what kind of length of time a solution would take.
It may take much longer than you think. A friend of mine was in a similar situation and had to wait about six months for a response. However, the problem was still not solved. You should just stop worrying about it and buy new cards. This way you will save your time and earn more during this time.
