For the rears you can use OEM S14 hubs, you can find them for $100 and much better than aftermarket, and cheaper.
For fronts I wouldn't buy ebay and probably not Ichiba, there have been posted of the studs coming loose, and you shouldn't trust something that is so cheap yet so vital to the car and safety.
For sake of simplicity, I would try and find Attain hubs (expensive but really high quality) or Ichiba if you are on a low budget.
