Thank you all for all the good advice given.After having a good think about what you've all said i am going to get the Mavics rebuilt. The hubs are in excellent condition and of a good quality ( Miche).
As for these cheap wheels though i am also going to buy them and use them as winter wheels so i can keep the worst of the salt off the Mavics.. They've now been reduced to £45 for the pair ,so they will come in handy as a back up .
Many thanks again.
Much appreciated.
Johnny
