I have a pair of the Harris hubs in black (http://sheldonbrown.com/harris/fixed-hubs.html)
they are very nice, but I would suggest you look at On-One if you want cheap because Harris have a $100 minimum order +$35 carrage for overseas stuff. A pair of hubs, sprocket and lockring just nicely gets you there though if you do go with them.
