Its not hard to build a wheel, just find a good tutorial.. Obviously it won't be amazing but once you get the hang of it they won't be too bad, it also saves money.. i wouldn't bother getting a whole new wheel, if you didn't want to build your own. Just get your local bike shop to build a new rim with new spokes onto your existing hub, they'll probably charge about 25 quid for the wheel build and spokes.
